WebAug 15, 2000 · Topoisomerases are needed in all three phases of bacterial DNA replication: initiation at the origin of replication, elongation with progressive outward movement of the forks until they meet halfway around the chromosome, and termination, including the final disentanglement of the catenated daughter chromosomes.Bacterial … WebThe replication origin forms a Y shape, and is called a replication fork. The replication fork moves down the DNA strand, usually from an internal location to the strand's end. The result is that every replication fork has a twin replication fork, moving in the opposite direction from that same internal location to the strand's opposite end.
