Referring to Figure 7-20, answer the following questions:a. What is the DNA polymerase I enzyme doing?b. What other proteins are required for the DNApolymerase III on the left to continue synthesizingDNA?c.

Topoisomerase and helicase unwind and open the double helix in preparationfor DNA replication. When the double helix has been unwound, single-strand-binding proteinsprevent the double helix from re-forming. The ilustration is a representation of the so-calledtrombone model (named for its resemblance to a trombone owing to the looping of thelagging strand) showing how the two catalytic cores of the replisome are envisioned to interactto coordinate the numerous events of leading- and lagging-strand replication.LaunchPad ANIMATED ART: Loading- and lagging-strand synthesis
