Question

List the order in which the following proteins and enzymes are active in E. coli DNA replication: DNA pol I, SSB, ligase, helicase, DNA pol III, and primase.

Accepted Answer

Hi, everyone. Welcome back. Let's look at our next question. It says which of the following statements is incorrect regarding the DNA replication of E Coli voice A DNA polymerase one fills the gaps between the Okazaki fragments in the lagging strand. Well, this is true DNA Polymerase one is the enzyme that fills in those gaps. So choice a cannot be our answer. Choice. B says heal a case unwinds the DNA structure to form a replicating fork. Well, this is also true that heli case as we see in the name unwinds the DNA helix to be able to allow replication to take place on the separated strands. So not our answer. Choi says DNA polymerase three synthesizes short R N A primers on the single stranded DNA template to provide a three prime O H group. Well, this one is not correct, It's not DNA Polymerase three, but primate that synthesizes those R N A primers. So this is going to be our answer since we're looking for an incorrect statement. But to be thorough, let's look at our last answer. Choice. Choice D says Ligase joins the Okazaki fragments by catalyzing the formation of phospho Dier bonds between adjacent nucleotides. And this is also true, you have polymerase one filling in the gaps and then ligase joining the fragments together with that final phospho dier bond. So also not our answer. So again, which of the following statements is incorrect regarding the DNA replication of E coli choice C DNA polymerase three synthesizes short R N A primers on the single stranded DNA template to provide a three prime O H group. See you in the next video.
