Problem

Which site (A or B) serves as the primer for the leading strand in region 2?

Shown is a schematic of replicatin DNA in a bacterial cell.

A. Site A

B. Site B

C. Site A or B

D. There isn't enough information

Solution

The leading strand of a replication process has its polymerase go in the 5' to 3' direction. This means that the template strand is in the 3' to 5' in that direction. Based on the Okazaki fragments of the lagging strand in region 1, the bottom strand is 3' to 5' from left to right.
