DNA polymerases I, III, and delta have important roles in replication. Which of these proteins have similar functions? Describe those similar functions that they share. Which one performs a different function and what is that function?
Homework Answers
Ans) DNA polymerase-I,III and delta has 3' ---> 5' exonuclease activity for the removal of RNA primer wheras DNA polymerase-I (small subunit) also has 5' -->3' exonuclease activity.
DNA polymerase-I,III, and delta can synthesize DNA from 5' --> 3' end.
DNA polymerase-I is used mainly for short fragment of DNA synthesis wheras DNA-Polymerase III is main replicating enzyme and has high catalytic processivity and high catalytic efficiency. DNA pol delta also has high processivity.

DNA Replication - Describe the process of DNA replication in a well-organized manner. Start with the helicase and go through the entire process, step by step. Use these terms correctly: Helicase, DNA primase, single stranded binding proteins, DNA polymerase I, DNA Polymerase III, leading strand, lagging strand, okazaki fragments, ligase, topoisomerase, sliding clamp, clamp loader. Please use correct descriptions of the enzyme function. For example, do not say, “seals nicks.” Tell me what “seals nicks” means.

RNA polymerases lack proofreading ability. Define proofreading ability and describe its importance in replication of DNA genomes. a. What advantage might its absence give RNA viruses like SARS-CoV-2? Following protein synthesis, RNA genome and proteins assemble to form virus particles that then bud into the endoplasmic reticulum (ER) lumen and then on to the Golgi apparatus. Next, they are transported via Golgi vesicles to the cell membrane, where they are released via exocytosis. Define ER, Golgi apparatus, and exocytosis,...
