Question

Which of the enzymes removes supercolingves which of the enzymes supercoling in replicating dna ahead of the replicating fork

Answer 1

Answer:The other type II enzyme in this organism, Topoisomerase IV (TopIV), acts to remove positive supercoils in advance of the replication fork and is a potent decatenase to resolve chromosomal intertwining.

Explanation:

gyrase

Measurements of the degree of DNA supercoiling in E. coli suggest that there is one negative supercoil for each 15 – 20 turns of the DNA helix. A second crucial function of gyrase is to remove the positive supercoils that form ahead of the growing fork during elongation of the growing strands.
