Question

Enzymes that modify the supercoiling of a DNA molecule are called
A) ligases.
B) primases.
C) transferases.
D) topoisomerases.
E) acetylases.

Accepted Answer

Enzymes that modify the supercoiling of a DNA molecule are called topoisomerases. Topoisomerases are enzymes that can change the supercoiling of DNA by cutting one or both strands of the helix, allowing the DNA to untwist or supercoil, and then rejoining the strands.
