Choose the correct option
DNA polymerases:
(A) all have a 5′–3′5′–3′ exonuclease activity for proofreading.
(B) are only found at replication forks.
(C) only polymerize in a 5′ to 3′5′ to 3′ direction.
(D) are all highly processive.
Homework Answers
I believe the correct answer to be:
Option C) only polymerizes in 5' to 3' direction.
This is a limitation of a DNA polymerase due to the structure of the nucleotide that it adds.

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...
