Q. The enzyme which helps to cut one strand of DNA duplex to release tension of coiling of two strands is
A) DNA ligase
B) DNA polymerase-I
C) Topoisomerase
D) Swielases (helicase or unwindases)
Explanation
The enzyme helicase unwinds the helix (by disrupting H bonds), while topoisomerase breaks and releases tension of strands of DNA. Topoisomerase also takes part in recombination.
