Possible Answers: Frameshift Missense Silent Nonsense Correct answer: Silent Question 2 What would be an immediate consequence for a cell with a mutant version of DNA polymerase III that has lost its proofreading function? Possible Answers: Cancer Inability to complete the cell cycle Inability to replicate DNA A higher rate of mutations during replication Correct answer: A higher rate of mutations during replication Question 3 Which of the following proteins are not situated within the core of the nucleosome? Possible Answers: H3 H2B H4 H2A H1 Correct answer: H1 Question 4 Which of the following classes of proteins are essential for DNA mismatch repair? Possible Answers: Nuclease All of these answers DNA ligase DNA polymerase Correct answer: All of these answers Question 5 Which enzyme is not involved in DNA replication? Possible Answers: Lipase Ligase Gyrase Helicase DNA polymerase Correct answer: Lipase Question 6 Which enzyme has a proofreading ability during DNA replication? Possible Answers: DNA polymerase DNA helicase DNA gyrase Primase Correct answer: DNA polymerase Question 7 You are trying to perform in vitro DNA replication on a small circular piece of DNA. You have DNA polymerase, Primase, Helicase, DNA ligase and all of their accessory proteins. You can get DNA replication to initiate but it never goes for very long without stopping. You visualize your small piece of DNA under an electron microscope and notice that after the initiation of replication, it looks all knotted up. What enzyme can you add to remedy this problem? Possible Answers: Telomerase Knottase Reverse Transcipase Topoisomerase RNA polymerase Correct answer: Topoisomerase Question 8 Which of the following characteristics is NOT seen in both DNA and RNA? Possible Answers: Adenine A double helix Read in the 5'-to-3' direction A pentose sugar Correct answer:
