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) |

|
(c) 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. |
