Which of the following statements is/are true regarding the initiation of DNA replication in bacteria?

A. Proteins bind to the DNA to begin separation of the strands.

B.	The strands are initially separated at GC-rich regions of DNA.

C.	Following initial separation, DNA helicase enzymes continue to separate the strands.

D.	All of the given answers

E.	Two of the given answers

Expert Solution

True statement regarding the initiation of DNA replication in bacteria is-

E. Two of the given answers-

i.e. A.Proteins bind to the DNA to begin separation of the strands.

and C.Following initial separation, DNA helicase enzymes continue to separate the strands ( helicases unwind the double helix by breaking the hydrogen bonds between complementary base pairs, while other proteins keep the single strands from rejoining).

Statement B. is incorrect because strands are initially separated at ''oriC'' region of DNA.

Which of the following statements about the general principles of chromosomal DNA replication in bacteria is FALSE? a. Chromosomal DNA replication is unidirectional and requires a distinct origin for each strand b. Both leading strand and lagging strand are synthesized simultaneously c. The leading strand is replicated continuously; the lagging strand is replicated discontinuously d. DNA or RNA can serve as primers e. It requires the replisome

Which of the following is/are true about DNA replication? A) Primase is needed to initiate DNA replication on both the leading strand and the lagging strand. B) The sliding clamp is loaded once on each DNA strand, where it remains associated until replication is complete. C) Telomerase carries its own DNA molecule to use as a primer at the end of the lagging strand. D) Primase requires a proofreading function that ensures there are no errors in the RNA primers...

Which of the following statements about these two DNA molecules is false? a) they are sister chromatids b) they are both double-stranded DNA helices c) they carry different sets of gene alleles d) they each consist of one "old" strand, which was the template strand, and one "new" strand, which was just synthesized 2) In which of the following molecular processes is the formation of Watson-Crick type base pairs between...

Why is it important that the initiation of DNA replication is carefully regulated? What is the proposed role of DnaA in this process? What extra proteins are necessary for lagging-strand synthesis that are not needed in leading-strand synthesis? Replication in eukaryotes is similar to that of prokaryotes. However initiation is different. Describe how initiation of replication occurs and how it is tied to the cell cycle. Explain in general terms how DNA replication can occur in a chromatin environment and...
