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
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 ,,...

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’).
What is/are the universal feature(s) of DNA replication?Choose all that apply. continuous replication of both strands of the double helix polymerization of a new strand in the 5' to 3' direction basepairing between nitrogenous bases semi-conservative replication release of PPi from incorporated nucleotides use of DNA primer to begin fragments Match the name of the protein/enzyme with its correct function during replication. You may use choices more than once or not at all. scan for errors in newly synthesized DNA...
