Question #3
Who is credited with the discovery of the shape of DNA?
Watson and Crick
Question #4
What is the basic structure of DNA called? Hint-twisted ladder
Double helix
Question #5
Complete the following diagram using the base-pairing rule
GTCGAC CAGCTG
Question #6
What does C stand for? Cytosine
Question #7
What does DNA stand for? Deoxyribose nucleic acid
Question #8
Are there any two people who have exactly the same DNA?
Yes, identical twins
Question #9
Why is DNA sometimes called the fingerprint inside your body?
Because no two peoples DNA is the same (except twins) and no two peoples fingerprints are the same
Question #10
What are the rails of the DNA strand made up of?
The sugar phosphate backbone is made up of the sugar (deoxyribose) and phosphate.
Question #11
What are the steps of the DNA strand are called?
Nitrogenous Bases
Question #12
In a DNA Strand A pairs with ____. T (thymine)
DNA Replication Questions
Question #13
Which enzyme is responsible for unwinding a DNA strand for replication?
DNA Helicase
Question #14
How does DNA Helicase unzip the strand?
It breaks the bonds (hydrogen) between the two nitrogenous bases
Question #15
When does DNA Replication occur during the cell cycle?
S-phase of interphase
Question #16
Why is it necessary for DNA Replication to occur?
I will take either of the following:To preserve the genetic code between cellsTo prepare for mitosis or meiosis
Question #17
In DNA replications, how many new double strands are made?
One
Question #18
DNA Replication follows the Semi-conservative model of replication, what does this mean?
It means that each strand is made up of one old strand (parent) and one new strand (daughter)
Question #19
In DNA Replication, which enzyme is responsible for laying down the complement bases?
DNA Polymerase
Question #20
Write the DNA Replication complement to this strand.
ATCGCCGATC TAGCGGCTAG
