Question 14 4 pts Which one of the following enzymes WILL NOT participate in DNA replication? O RNA ploymerase O DNA polymerase Ligase O Helicase Question 15 4 pts In DNA replication - if one DNA strand has nucleotide sequence as 5'ATGCITCCT3, The other strand of the DNA will have nucleotide sequence as and it will be synthesized in direction. OUACGAAGGA; 3' to 5' direction OTACGAAGGA; 3' to 5' direction OTACGAAGGA; 5' to 3' direction OTUCGUUGGU; 5' to 3' direction
Question 5 4 pts Which of the following statements in NOT true about DNA replication? DNA replication involves synthesis of multiple RNA primers DNA ligase is needed for successful DNA replication DNA replication requires deoxyribonucleotide triphosphates High fidelity of DNA replication is ensured by 5-3 exonuclease activity of DNA polymerase ! High fidelity of DNA replication is ensured by 3-5 exonuclease activity of DNA polymerases Next
What would be the effects on DNA replication if mutation of DNA polymerase III caused it to lose each of the following activities: 1. 5' to 3' polymerase activity 2. 3' to 5' exonuclease activity:
1. DNA Structure and Replication fill in the blanks. 10pts and , have two nitrogenous rings and are a. The bases, called direction and reads the b. DNA Polymerase synthesizes new DNA in the template DNA strand in the direction. c. DNA polymerases use -exonuclease activity to proofread newly synthesized DNA. Whereas, DNA Pol I uses _-exonuclease activity to remove RNA primers. d. The enzyme telomerase synthesizes using as a template. e. DNA Replication begins at the and two ,,...
Explain the process of DNA replication, including what enzymes are involved. Compare this with Polymerase Chain Reaction and Sanger Sequencing.
21. In DNA replication, new nucleotides are added a. To the 5' end of each nascent strand b. To the 3'end of each nascent strand To both ends of each nascent strand d. To the 5' end of the continuous strand and the 3' end of the discontinuous strand e. To the end of the continuous strand and the end of discontinuous strand fragments 22. DNA unwinding is done by a. Ligase b. Helicase c. Topoisomerase dHexonuclease 23. Proofreading of...

Match the molecule or term with its description Question Selected Match semi-conservative A. mechanism of replication for viral DNA theta B. mechanism of replication for circular bacterial DNA rolling circle C. mechanism of DNA replication determined by Meselson and Stahl OriC D. where the two new DNA strands are synthesized A-T rich region E. where DNA unravels when initiator proteins bind OriC replication fork F. where replication begins for the bacterial chromosome leading strand G. the new DNA strand...
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...
Explain the 5’-to-3’ directional activity of DNA polymerase. Please give an explanation for the inability of this enzyme to synthesize DNA in opposite direction (3’-to-5’).
