Question 8 0/ 10 pts DNA polymerase I and DNA polymerase III both have polymerase I has but only DNA 5'— 3' exonuclease activity: 375'exonuclease activity 5'— 3 polymerase activity: 3—5' polymerase activity 3-5 polymerase activity: 5 — 3' polymerase activity Correct Answer 3'5'exonuclease activity: 5'— 3' exonuclease activity You Answered 5'— 3 polymerase activity: 3'-5'exonuclease ...

DNA polymerase I has 5'-3' polymerase activity, 5'-3' exonuclease activity, and 3'-5' exonuclease activity necessary for DNA replication. Mutations in the gene that encodes DNA polymerase I may cause the enzyme to lose these activities. Match the consequence of a loss-of-function mutation in DNA polymerase I to the corresponding lost activity.

Question: DNA polymerase 1, DNA ligase, and topoisomerase 1 usse an activated intermediate to catalyze the formation of phosphodiester bonds with the release of a leaving group. Match the activated intermediate and the leaving group to each enzyme

Briefly describe what each of these exonuclease functions is used for during DNA replication and why it is necessary. (4 points) 1b) In addition to DNA polymerase I, cells also have DNA polymerase III, which lacks the 5' 3' exonuclease activity and the strand displacement ability of DNA polymerase I.

Multiple choice questions: 1) For DNA Polymerase III to work, which of these components has to act first? (A. Conservative replication, B. Newly replicated strand, C.Primase, D. RNA, E.Mutation rate) 2) The double helix of DNA is wrapped about 1 3/4 times around which of these components? (A. Helicase, B. DNA polymerase III, C. DNA polymerase I,

1. Which activity of DNA polymerase is responsible for its ability to proofread newly synthesized DNA? 2. How many mutations would you expect to see in the human genome (6 x 1 0 9) if mismatches could not be repaired? Hint: Because of tautomeric shiftinduced mismatches, DNA replication inherently can be no more accurate than 1 0 − 4 mutations ...

Identify the key function of DNA polymerase 1 in the process of DNA replication, focusing particularly on its role in removing RNA nucleotides and replacing them with DNA.

Question: 1. DNA polymerase III synthesizes the majority of the DNA during DNA replication Only in the leading strand Only in the lagging strand This occurs in both the leading and the lagging strands This is a false statement 2.
