how is the supercoiling of dna corrected during the replication process?
how is the supercoiling of dna corrected during the replication process?
a. the entire dna molecule is uncoiled prior to the start of the replication process.
b. topoisomerase clips and untwists small sections of supercoiled dna molecules.
c. dna ligase breaks bonds in the sugar - phosphate backbones to prevent supercoiling.
d. helicase separates the strands and snips them into smaller sections when supercoiling gets too tight.

Explanation:

Topoisomerases relieve DNA super - coiling during replication by cutting and rejoining DNA strands to manage the tension. Option A is inefficient, DNA ligase (option C) seals nicks not prevent supercoiling, and helicase (option D) unwinds DNA not correct supercoiling in this way.

Answer:

B. Topoisomerase clips and untwists small sections of supercoiled DNA molecules.
