There are special proteins that help to open up DNA double helix in front of the replication fork. These proteins are `:`

A

DNA ligase

B

DNA gyrase

C

DNA polymerase I

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
DNA gyrase (DNA topoisomerase II) provides a swivel in front of each replication fork. As helicase unwinds the DNA at the replication forks, the DNA ahead of it becomes over wound and positive supercoils form.
