2.) True or False: DNA's four nitrogenous bases are adenine, cytosine, uracil, and guanine.
The correct answer is ....
3.) How are the complimentary base pairs held together?
A.) Covalent bonds
B.) Deoxyribose
c.) Hydrogen Bonds
D.) Phosphoric acid
The correct answer is ....
4.) True or False: DNA replication is semiconservative
The correct answer is ....
5.) True or False: During DNA replication, the leading strand is
made as a continuous piece, while the lagging strand is
made in small pieces.
The correct answer is ....
6.) In addition to DNA
polymerase, what other enzymes are required in DNA replication?
A.) Oxidoreductases,DNA primase, RNA polymerase,
and protease
B.) Transferases, DNA ligase,DNA primase,
and isomerases
C.) DNA primase, lyases, transferases,
and hydrolases

The correct answer is ....
7.) How does DNA Polymerase NOT work?
A.) They can't start making a DNA chain from scratch, but require a primer
B.) They can add nucleotides to both the 3' end and the 5' end of a DNA strand
C.) They always need a template
D.) They proofread their work, by removing the vast majority of
"wrong" nucleotides that are accidentally added to the chain
The correct answer is ....
8.) Complete the blank: The addition of nucleotides requires energy. This energy comes from __________, which have
three phosphates attached to them.
The correct answer is ....
9.) What happens when the origin of replication is recognized and what forms?
The correct answer is ....
10.) Where will the DNA polymerases bind?
A.) the 3' end of an existing DNA strand
B.) the 3' end of the new DNA strand
C.) the 5' end of an existing DNA strand
D.) the 5' end of the new DNA strand
The correct answer is ....
11.) True or False: The lagging strand is easier to make because the strand is made in fragments.
The correct answer is ....
12.) Complete the Blank: The small fragments that are caused due to the lagging strand are called ____________,
named for the Japanese scientist who discovered them.
The correct answer is ....
13.) What is the job of the sliding clamp?
A.) It prevents the DNA double helix ahead of the replication
fork from getting too tightly wound as the DNA is opened up
B.) It is the origin of
replication
C.) It seals the nicks that remain after the primers are
replaced
D.) It holds the DNA polymerase lll molecules in place as they synthesize DNA.
The correct answer is ....
14.) True or False: DNA is known to be anti-parallel
The correct answer is ....
15.) What happens when the RNA primers are removed?
