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?

Solutions

Expert Solution

•DNA Polymerase 1This repair polymerase is involved in excision repair with both 3'–5' and 5'–3' exonuclease activity and processing of Okazaki fragments generated during lagging strand synthesis

•DNA polymerase III has 3 functions: Selects and adds free deoxyribonucleoside triphosphates complementary to the DNA template strand..

•Pol δ primarily replicates the lagging strand; however, recent evidence suggested that Pol δ might have a role in replicating the leading strand of DNA as well.

polymerase divide into families on the basis of sequence homology  

DNA polymerase delta and 3 have same feature and function that is 3 to 5 exonuclease proofreading.

I am confused with the end replication problem. So, at the end DNA polyermase III is unable to bind to the end because there is a missing of a 3' hydroxyl group. Given that, why can't a DNA primase simply add a primer at the end in which DNA polymerase III binds to it and finishes the replication and then a DNA polymerase I binds to the primer and replaces it with DNA and therefore solving the problem? Can someone...

You are curious how the three eukaryotic DNA polymerases assemble at the replication origin. To study this, your lab has purified DNA polymerases, a DNA template with a replication origin, and a procedure for measuring DNA-bound polymerases. You carry out experiments to see the effect of leaving out a DNA polymerase and obtain the results in the table. POLYMERASES INCLUDED DNA-BOUND POLYMERASE α, ε ε α, δ δ δ, ε δ, ε α, δ, ε α, δ, ε 4.
