Question 6 1 pts 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? O 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...
Question 5 1 pts The enzyme helicase is an important part of the replication machinery, but its use now requires specifically the activity of the following enzyme: Topoisomerase ODNA polymerase Sliding clamp Primase Ligase Question 7 1 pts Much of replication can be studied using extracts from wild type (normal) yeast cells that supply all of the essential components. Compared to wild type extracts, if you use an extract that is missing the sliding clamp AND ligase, what do you...

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.
Which of the following is not a property of DNA polymerase? a. It is associated with a sliding clamp only on the leading strand b. It requires a primer to work c. Its exonuclease activity is involved in proofreading d. It adds dNTPs only in the 5' to 3' direction
