In DNA replication, which of the following enzymes is required for separating the DNA molecule into two strands?
A
DNA gyrase
B
DNA polymerase
C
Helicase
D
Single strand binding protein
E

The enzyme helicase unwinds DNA. It depends on several other proteins to make the unwinding run smoothly, however. Single-strand binding protein holds the single stranded DNA in place, and topoisomerase helps relieve tension at the replication fork.
