1.Each strand of a DNA double helix serves as a
template for synthesizing a new complementary strand in the 5โ€™ to
3โ€™-direction. This follows the mechanism of Semi-conservative
replication.

a.True

b.False

2.

2.At each replication origin, there are how
many forks?

a.One

b.Two

c.Three

d.Four

e.None of the above
are correct

3.What would happen if the Sliding Clamp and
Sliding Clamp Loader were absent in the cell during the process of
replication?

a.The DNA polymerase
would keep falling off the DNA template

b.The processivity of
the DNA polymerase would be increased

c.Replication would
occur at the same rate in their absence

d.There would be
increased primase activity

4.To generate a continuous new DNA strand free
of RNA segments, the activity of the following enzyme(s) are
needed:

a.Nuclease

b.Repair
Polymerase

c.DNA ligase

d.ALL of the above

e.NONE of the
above5

5.The eukaryotic DNA
polymerase needs a 3โ€™-hydroxyl group in order to catalyze the
addition of incoming nucleotides to the growing DNA chain. Thus,
DNA polymerases need the help of the Primase which will add a short
segment of RNA.

a.True

b.False
