Which of the following is not a property of DNA polymerase?
a.) It requires a primer to work
b.) Its exonuclease activity is involved in proofreading
c.) It is associated with a sliding clamp both on the leading and lagging strands
d.) It adds dNTPs only in the 3' to 5' direction
Homework Answers
d.) It adds dNTPs only in the 3' to 5' direction.
The DNA polymerase moves along the DNA (or RNA) template, extending the primer in the 5′ → 3′ direction according to the Watson–Crick base pairing rule, hence dNTPs are adds in 5' to 3' direction

You created a mutant form of DNA polymerase in which the 3'to 5' exonuclease (proofreading] function has been destroyed, although its polymerase activity is still fine. Which of the following properties do you expect the mutant polymerase to have? It will polymerize in both the 5-to-3' direction and the 3'-to-5' direction. o It will likely make a new strand of DNA (same length) slower than a normal polymerase. It will be more likely to generate thymidine dimers. As it gets...
