Daily TAKS Connection:Replication, Transcription, Translation
BIO(6): The student knows that the structures and functions of nucleic acids in the mechanisms of genetics. The student is expected to:
(B) Explain replication, transcription, and translation using models of DNA and RNA.
Foldable Instructions
Construct a three tab foldable Materials:
Foldable handout Scissors Pen Colored
pencils/crayons
Instructions: Hotdog fold paper
along center line Cut tabs from edge
to center along dotted lines
DNA Replication Notes
Record the following notes under the flap labeled “Replication” -
DNA synthesis DNA → DNA Occurs in the nucleus
1. DNA double helix unwinds; separates at hydrogen bond between base pairs
2. DNA polymerase adds base pairs to both strands
Adenine complements Thymine
Guanine complements Cytosine
3. Two “New” DNA molecules formed– one strand original, one strand new
Question 1 (Answer questions from notes on the back of your foldable.
DNA passes information to new DNA during the process of —
a. replication
b. transcription
c. translation
d. osmosis
Question 2
Which of the following must occur before DNA replication can take place?
a. Translation of DNA into amino acids
b. Separation of the DNA molecule intocodons
c. Transformation of DNA into RNA
d. Separation of the DNA double helix
Question 3
Part of a DNA strand is represented in the diagram shown. In order for DNA to replicate, the strand must separate at which of the following locations?
a. Between every phosphate-sugar pair
b. Between the eight sugar-base pairs
c. Between the four nitrogenous base pairs
d. Between any two chemical bonds
Question 4
If the template of a strand of DNA is 5' TCTACGTAG 3', the complementary strand will be —
a. 3' TCTACGTAG 5'
b. 5' CTACGTAGA 3'
c. 3' AGATGCATC 5'
d. 5' AGACGTCTA 3'
Transcription Notes
Record the following notes under the flap labeled “Transcription” -
RNA synthesis DNA → RNA Occurs in the nucleus Adenine from DNA
complements Uracil in RNA Thymine from DNA
complements Adenine in RNA
Guanine from DNA complements Cytosine in RNA
Cytosine from DNA complements Guanine in RNA
Question 5
DNA passes information to RNA during the process of —
a. replication
b. transcription
c. translation
d. osmosis
Question 6
3' CGGUAU 5'
This is a short section of mRNA. Which DNA code probably produced this section of RNA?
a. 3' GCCTUT 5'
b. 5' GCCAUT 3'
c. 3' ATTGCC 5'
d. 5' GCCATA 3'
Question 7
Which of these represents the DNA segment from which this section of mRNA was transcribed?
a. ACTAAG
b. TCUTTG
c. GAAUCU
d. UCCTGA
Question 8
The diagram shows how an mRNA molecule is synthesized. What would be the most likely result if a bacterial infection stopped the production of the RNA polymerase?
a. A protein could not be manufactured.
b. A lysosome would digest the cell.
c. Osmosis would not occur in the cell.
d. Dehydration could be prevented in the cytoplasm.
Translation Notes
Record the following notes under the flap labeled “Translation” -
Protein synthesis RNA → protein Occurs at the
ribosomes Codons (3 base
sequence) code for amino acids
Use codon chart to determine amino acid
Amino acids link together to form protein
Activity
Using the codon chart, transcribe the RNA nucleotide
sequence below:
UUCACGGAAUGG
Question 9
RNA is used to code for proteins during the process of —
a. replication
b. transcription
c. translation
d. osmosis
Question 10
Translation (protein synthesis) takes place in a cell at the –
a. nucleus
b. mitochondria
c. ribosome
d. cell membrane
