Which of the Following Enzymes Catalyze the Unwinding of the DNA

Question

Which of the following enzymes catalyze the unwinding of the DNA double helix?
A)topoisomerases
B)helicases
C)ligases
D)gyrases

Accepted Answer

Helicases are enzymes that catalyze the separation of the two DNA strands by breaking the hydrogen bonds between the complementary base pairs, resulting in the unwinding of the double helix. Topoisomerases, gyrases, and ligases are involved in DNA replication and repair but do not directly participate in the unwinding process.
