DNA Fingerprinting

Figure 1: Examples of restriction enzymes and the organism of origin.

When first introduced, DNA fingerprinting (also called DNA profile analysis or DNA typing) involved the electrophoretic analysis of DNA fragment sizes generated by restriction enzymes. In contrast to more conventional methodologies, such as blood typing, which excludes suspects, traditional DNA fingerprinting provides accurate, unambiguous identification of the source of DNA samples.

Variations in DNA sequences between individuals as determined by dif-ferences in restriction enzyme cleavage patterns are known as restriction fragment length polymorphisms (RFLPs). RFLPs are a manifestation of the unique molecular genetic profile, or “fingerprint”, of an individual’s DNA.

Restriction Enzyme Organism

Restriction enzymes are endonucleases that catalyze cleavage of phos-phate bonds. They require Mg+2 for activity and generate a 5 prime (5') phosphate and a 3 prime (3') hydroxyl group at the point of cleav-age. The distinguishing feature of restriction enzymes compared to other endonucleases is that they only cut at very specific sequences of bases. Restriction enzymes are produced by many different species of bacteria (including blue-green algae). Over 3,000 restriction enzymes have been discovered and catalogued.

Restriction enzymes are named according to the organism from which they are isolated. The first letter of the genus followed by the first two letters of the species (Fig. 1). Only certain strains or sub-strains of a particular species may produce restriction enzymes. The type of strain or substrain sometimes follows the species designation in the name. Finally, a Roman numeral is used to designate one out of several restriction enzymes produced by the same organism.

A restriction enzyme requires a specific double-stranded recognition sequence of nu-cleotide bases to cut DNA. Recognition sites are generally 4 to 8 base pairs in length and cleavage occurs within or near that site. Rec-ognition sites are frequently symmetrical, i.e., both DNA strands in the site have the same base sequence when read 5' to 3' and the cleavage positions are indicated by arrows. Such sequences are called palindromes.

Consider the recognition site and cleavage pattern of Eco RI as an ex-ample. Eco RI causes staggered cleavage of its site. The resulting ends of the DNA fragments are called “sticky” or “cohesive” ends.

The size of DNA fragments generated depends on distances between the recognition sites. In general, the longer the DNA molecule, the greater the probability that a given recognition site will occur. The DNA of an av-erage human chromosome is very large, containing over 100 million base pairs. A restriction enzyme having a 6-base pair recognition site, such as Eco RI, would be expected to cut human DNA into approximately 750,000 different fragments.

No two individuals have exactly the same pattern of restriction enzyme recognition sites. There are several reasons for this fact that exists in a population. Alleles are alternate forms of a gene that result in alternative expressions of genetic traits that can be dominant or recessive. Chromo-somes occur in matching pairs, one of maternal and the other of paternal origin. The two copies of a gene at a given chromosomal locus represent a composite of parental genes and constitute an individual’s unique genotype. It follows that alleles have differences in their base sequences which consequently creates differences in the distribution and frequen-cies of restriction enzyme recognition sites. Other differences in base sequences between individuals can occur because of mutations and deletions. Such changes can also create or eliminate a restriction endo-nuclease palindromic site. The example in Figure 2 shows how a silent mutation can eliminate a recognition site but leave a protein product unchanged.

Individual variations in the distances between recogni-tion sites in chromo-somal DNA are often caused by interven-ing repetitive base sequences. Rep-etitious sequences constitute a large fraction of the mam-malian genome and have no known genetic function. These sequences can occur between

genes or are adjacent to them. They are also found within introns. Ten to fifteen percent of mammalian DNA consists of sets of repeated, short sequences of bases that are tandemly arranged in arrays. The length of these arrays (the amount of repeated sets) varies between individuals at different chromosomal loci.

TGTTTA|TGTTTA|TGTTTA|.........variable number

When these arrays are flanked by recognition sites, the length of the repeat will determine the size of the restriction enzyme fragment gener-ated. Several types of short, repetitive sequences have been cloned and sequenced.

AgAROSE gEl ElEctROphORESIS

Agarose gel electrophoresis is used to analyze DNA fragments generated by restriction enzymes. Agarose gels consist of microscopic pores that act as a molecular sieve. DNA fragments are loaded into wells made in the gel during casting. Since DNA has a negative charge at neutral pH, it migrates through the gel towards the positive electrode during elec-trophoresis. DNA fragments are separated by the gel according to their size, charge and shape. DNA fragments are linear and the ratio of mass to charge is the same. Therefore, only the size of the fragment affects the mobility. The smaller the fragment the faster it migrates. After electropho-resis, DNA can be visualized by staining.

Restriction enzyme cleavage of relatively small DNA molecules, such as plasmids and viral DNAs, usually results in discrete banding patterns of DNA fragments after electrophoresis. However, cleavage of large and complex DNA, such as human chromosomal DNA, generates many differ-ently sized fragments that the resolving capacity of the gel is exceeded.

Consequently, the cleaved chromosomal DNA is visualized as a smear after staining and has no obvious banding patterns.

SOUthERN blOt ANAlySIS

RFLP analysis of genomic DNA is facilitated by Southern blot analysis. After electrophoresis, DNA fragments in the gel are denatured by soaking in an alkali solu-tion. This causes double-stranded fragments to be converted into single-stranded form (no longer base-paired in a double helix). A replica of the electrophoretic pattern of DNA fragments in the gel is made by transfer-ring (blotting) them to a sheet of nitrocellulose or nylon membrane (Figure 3). This is done by plac-ing the membrane on the gel after electropho-resis and transferring DNA

DNA Fingerprinting

fragments to the membrane by capillary action or electrotransfer. DNA, which is not visible, becomes permanently adsorbed to the membrane, that can then be manipulated easier than gels.

Analysis of the blotted DNA is done by hybridization with a labeled oligo-nucleotide DNA probe. The probe is a DNA fragment that contains base sequences that are complementary to the variable arrays of tandemly repeated sequences found in the human chromosomes. Probes can be labeled with reporter molecules that are used for detection. A solution containing the single-stranded probe is incubated with the membrane containing the blotted, single-stranded (denatured) DNA fragments. Under the proper conditions, the probe will only base pair (hybridize) to those fragments containing the complementary sequences. The mem-brane is then washed to remove excess probe. Only DNA fragments that

are hybridized to the probe will reveal their positions on the membrane. If the probes are isotopically labeled, the hybridized fragments will appear as discrete bands (fingerprint) on the film and are in the same relative po-sitions as they were in the agarose gel after electrophoresis. Only specific DNA fragments of the hundreds of thousands of fragments present, will hybridize with the probe because of the selective nature of the hybridiza-tion process.

In forensic analysis, DNA samples can be extracted and purified from specimens of skin, blood stains, semen, or hair roots collected at the crime scene. RFLP analyses performed on these samples is then compared to those performed on samples obtained from the suspect. If RFLP patterns match, it is beyond reasonable doubt that the suspect (or biological ma-terial from the suspect, such as blood) was at the crime scene. In forensic DNA fingerprinting, different sets of probes hybridized to different types

of repetitious sequences are used in DNA profile analysis in order to satisfy certain statistical criteria for positive identification.

pOlymERASE chAIN REActION (PCR)

RFLP-based DNA fingerprinting analysis has been overtaken by the Polymerase Chain Reaction (PCR) because of two important advantages. The first is the sensitivity of PCR, which allows for DNA fingerprinting identification using much smaller amounts of DNA since PCR amplifies DNA. A second advantage is the speed of PCR analysis, which allows critical questions to be answered more quickly as compared to Southern Blot analysis.

PCR amplification requires the use of a thermostable DNA polymerase, such as Taq polymerase. Purified from a bacte-rium known as Thermus Aquaticus that inhabits hot springs, Taq polymerase is commonly used in PCR because it remains stable at near-boiling temperatures. Also included in the PCR reaction are the four deoxynucleotides (dATP, dCTP, dGTP, and dTTP) and two synthetic oligonucleotides, typically 15-30 base pairs in length, known

as "primers". These components, together with the DNA to be amplified, are incubated in an appropriate buffer that contains Mg2+. The primers are designed to correspond to the start and end of the DNA to be ampli-fied, known as the "target".

The PCR reaction mixture (which contains the DNA polymerase, buffer, de-oxynucleotides, primers, and template) is subjected to sequential heating/cooling cycles at three different temperatures (Figure 5).

• In the first step, the template is heated to near boiling (92° - 96°C.) to denature or "melt" the DNA. This step, known as "denaturation" disrupts the hydrogen bonds between the two complimentary DNA strands and causes their separation.

• In the second PCR step, the mixture is cooled to a temperature that is typically in the range of 45° - 65°. In this step, known as "annealing", the primers, present in great excess to the template, bind to the sepa-rated DNA strands.

• In the third PCR step, known as "extension", the temperature is raised to an intermediate value, usually 72°C. At this temperature the Taq polymerase is maximally active and adds nucleotides to the primers to complete the synthesis of the new complimentary strands.

DNA fingerprinting analysis has become increasingly significant in court cases involving murder, rape, physical battery, and other types of crimes. Jurors are often asked to determine the validity of DNA evidence, result-ing in both acquittals and convictions of suspected criminals. To ensure greater accuracy, scientists have incorporated standardization proce-dures in DNA analysis. Standard DNA Fragments are used to determine the exact size of individual DNA fragments in a DNA fingerprint. It is generally accepted that DNA fingerprints are identical only in the case of identical twins.

In this experiment, emphasis is placed on concepts related to RFLP analy-sis. The experiment activities will focus on the identification of DNA by analyzing restriction fragmentation patterns separated by agarose gel electrophoresis.

6. Heat the mixture to dissolve the agarose powder. The final solution should appear clear (like water) without any undissolved particles.

A. Microwave method:

• Cover the flask with plastic wrap to minimize evaporation.

• Heat the mixture on High for 1 minute.

• Swirl the mixture and heat on High in bursts of 25 seconds until all the agarose is completely dissolved.

B. Hot plate method:

• Cover the flask with aluminum foil to prevent excess evapora-tion.

• Heat the mixture to boiling over a burner with occasional swirling. Boil until all the agarose is completely dissolved.

Check the solution carefully. If you see "crystal" particles, the agarose is not completely dissolved.


At high altitudes, it is recommended to use a microwave oven to reach boiling temperatures.

7. Cool the agarose solution to 60°C with careful swirling to promote even dissipa-tion of heat. If detectable evapora-tion has occurred, add distilled water to bring the solution up to the original volume marked on the flask in step 6.

After the gel is cooled to 60°C:

If you are using rubber dams, go to step 9.

If you are using tape, continue with step 8.

8. Seal the interface of the gel bed and tape to prevent the agarose solution from leaking.

• Use a transfer pipet to deposit a small amount of cooled agarose to both inside ends of the bed.

• Wait approximately 1 minute for the agarose to solidify.

9. Pour the cooled agarose solution into the bed. Make sure the bed is on a level surface.

10. Allow the gel to completely solidify. It will become firm and cool to the touch after approximately 20 minutes.

DO NOT POUR BOILING HOT AGAROSE INTO THE GEL BED.

Hot agarose solution may irreversibly warp the bed.

11. After the gel is completely solidified, carefully and slowly remove the rubber dams or tape from the gel bed.

Be especially careful not to damage or tear the gel wells when remov-ing the rubber dams. A thin plastic knife, spatula or pipet tip can be inserted between the gel and the dams to break possible surface ten-sion.

12. Remove the comb by slowly pull-ing straight up. Do this carefully and evenly to prevent tearing the sample wells.

13. Place the gel (on its bed) into the electrophoresis chamber, properly oriented, centered and level on the platform.

ible as dark blue bands against a lighter blue background. When the gel is completely destained, the larger DNA bands will become sharper and the smaller bands will be visible. With additional destaining, the entire back-ground will become uniformly light blue.

10. Carefully remove the gel from the destain solution and examine the gel on a Visible Light Gel Visualization System. To optimize visibility, use the amber filter provided with EDVOTEK equipment.

11. If the gel is too light and bands are difficult to see, repeat the staining and destaining procedures.

* Destaining Notes

• Warmed distilled water at 37°C will accelerate destaining. Destaining will take longer with room temperature water.

• DO NOT EXCEED 37°C ! Warmer temperatures will soften the gel and may cause it to break.

• The volume of distilled water for destaining depends upon the size of the tray. Use the smallest tray available that will accommodate the gel. The gel should be completely submerged during destaining.

• Do not exceed 3 changes of water for destaining. Excessive destaining will cause the bands to be very light.

Notes to the Instructor:

This experiment simulates a forensic case in which DNA samples from a hypothetical crime scene and suspects are digested by six-base cutting enzymes (Eco RI and Hind III). The objective is to analyze suspect DNA fingerprint patterns and compare them with “crime scene” samples. Each DNA sample will be cleaved with two restriction enzymes in separate reactions, and pairs of fragmentation patterns will serve as the fingerprints. The DNA fragmentation patterns will be analyzed in the stained agarose gel, without the need for Southern blot analysis.

This experiment module contains biologicals and reagents for six groups. The experimental procedures consist of two major parts: 1) restriction enzyme digestion of DNA, which is followed by 2) agarose gel electropho-resis.

Each laboratory group receives two predigested, ready-for-electrophore-sis “crime scene” samples and standard DNA fragments (markers). Four additional DNA samples are generated by performing restriction enzyme digestion reactions on the DNAs of two suspects.

If you have six (6) electrophoresis units, one for each of the six lab groups, electrophoresis can be performed simultaneously by all six groups. Alter-natively, some lab groups can store their samples at 4°C and perform the electrophoresis at different times.

AppROxImAtE tImE REqUIREmENtS

1. Prelab preparation and dispensing of biologicals and reagents take approximately 1-2 hours.

2. The approximate time required for students to perform the restric-tion enzyme digestion and prepare samples for electrophoresis is 50 minutes. The incubation time for restriction enzyme digestion may be extended to 60 minutes.

3. gel preparation: Whether you choose to prepare the gel(s) in ad-vance or have the students prepare their own, allow approximately 30-40 minutes for this procedure. Generally, 20 minutes of this time is required for gel solidification.

4. practice gel loading: If your students are unfamiliar with using micropipets and sample loading techniques, a practice activity is sug-gested prior to conducting the experiment. EDVOTEK electrophoresis experiments contain a tube of practice gel loading solution for this purpose. Casting of a separate practice gel is highly recommended. This activity can require anywhere from 10 minutes to an entire labora-tory session, depending upon the skill level of your students.

Notes to the Instructor:

5. conducting Electrophoresis: The approximate time for electrophoresis

will vary from approximately 15 minutes to 2 hours depending upon various factors. Dif-ferent models of electrophoresis units will sep-arate DNA at different rates depending upon its configuration and the distance between the two electrodes. Generally, the higher the voltage applied the faster the samples migrate. However, the maximum amount of voltage significantly depends upon the design of the electrophoresis apparatus and should not exceed manufacturer's recom-mendations. Time and Voltage recommen-dations for EDVOTEK equipment are outlined in Table C.

gEl StAININg AND DEStAININg AFtER ElEctROphORESIS This experiment features InstaStain® Blue for gel staining after electro-phoresis. It is a proprietary new staining method which saves time and reduces liquid waste. EDVOTEK also offers InstaStain® Ethidium Bromide (InstaStain® EtBr) and Protein InstaStain® for staining Protein polyacrylam-ide gels.

Two options are provided for using the InstaStain® Blue cards.

• Method 1: One-step Staining and Destaining with InstaStain® MetBlue

Agarose gels can be stained and destained in one easy step, which can be completed in approximately 3 hours, or can be left in liquid overnight.

• Method 2: Staining with InstaStain® Blue

Using InstaStain® Blue cards requires approximately 5-10 minutes for staining. DNA bands will become visible after destaining for approxi-mately 20 minutes, and will become sharper with additional destain-ing. For the best photographic results, allow the gel to destain for sev-eral hours to overnight. This will allow the stained gel to "equilibrate" in the destaining solution, resulting in dark blue DNA bands contrasting against a uniformly light blue background.

pREpARINg AgAROSE gElS preparing gels for electrophoresisThere are several options for preparing agarose gels for the electrophore-sis experiments:

1. Individual Gel Casting: Each student lab group can be responsible for casting their own individual gel prior to conducting the experiment.

2. Batch Gel Preparation: A batch of agarose gel can be prepared for sharing by the class. To save time, a larger quantity of UltraSpec-Agarose can be prepared for sharing by the class. See instructions for "Batch Gel Preparation".

3. Preparing Gels in Advance: • Gels may be prepared ahead and stored for later use. Solidi-

fied gels can be stored under buffer in the refrigerator for up to 2 weeks.

Do not store gels at -20°C. Freezing will destroy the gels.

• Gels that have been removed from their trays for storage, should be "anchored" back to the tray with a few drops of hot, molten agarose before placing the gels into the apparatus for electro-phoresis. This will prevent the gels from sliding around in the trays and the chambers.

4. Heat the agarose solution as outlined previously for individual gel preparation. The heating time will require adjustment due to the larger total volume of gel buffer solution.

5. Cool the agarose solution to 60°C with swirling to promote even dissipation of heat. If evaporation has occurred, add distilled water to bring the solution up to the original volume as marked on the flask in step 3.

6. Dispense the required volume of cooled agarose solution for casting each gel. The volume required is dependent upon the size of the gel bed.

7. Allow the gel to completely solidify. It will become firm and cool to the touch after approximately 20 minutes. Then proceed with prepar-ing the gel for electrophoresis.

Note: The UltraSpec-Agarose™ kit com-ponent is often labeled with the amount it contains. In many cases, the entire contents of the bottle is 3.0 grams. Please read the label carefully. If the amount of agarose is not specified or if the bottle's plastic seal has been broken, weigh the agarose to ensure you are using the correct amount.

Study Questions and Answers

1. which suspect DNA matches that found at the crime scene? Does this automatically mean that the suspect is guilty?

The DNA profile for Suspect 2 matches the DNA obtained at the crime scene. The results do not automatically mean that the suspect is guilty (see answers to questions 2 and 3).

2. what possible experimental problems could occur to invalidate the results?

Experimental problems which could invalidate the results include con-tamination of DNA samples or incomplete cleavage by the restriction enzymes.

3. If only Restriction Enzyme 1 was used, would the interpretation be the same?

The interpretation would not be the same if only one enzyme were used. For instance, both suspects have the same fragment pat-tern with Restriction Enzyme 1. The results would be inconclusive. As covered in the background information, in practice, several different probes containing different types of repetitious sequences are used in DNA profile analysis in order to satisfy certain statistical criteria for posi-tive identification. The use of different restriction enzymes allow for accuracies in positive identifications of greater than one in 100 million.
