What is the function of the enzyme topoisomerase in DNA replication?
A) relieving strain in the DNA ahead of the replication fork caused by the untwisting of the double helix
B) detecting the shape of the template base's surface to help recruit the appropriate nucleotide to pair
C) reattaching the hydrogen bonds between the base pairs in the double helix
D) building RNA primers using the parental DNA strand as a template

Question

Quizplus · Accepted Answer

Topoisomerase relieves the strain caused by the unwinding of the double helix ahead of the replication fork, preventing supercoiling and making the DNA more accessible for replication.
