Question

Which enzyme reduces tension during unwinding of DNA helix in front of the
replication fork
(A) Helicase
(B)
Ligase
(C) Topoisomerase
(D) Primase​

Answer 1

Answer:

Helicase is the enzyme that reduces tension during unwinding of DNA helix in front of the

replication fork

Answer 2

Answer:

DNA denaturation by helicases creates topological stress in the helical DNA structure which is relieved by the action of topoisomerases. These enzymes transiently break both DNA strands of one chromosome thereby, making the other chromosome pass through the break and relieve the stress.
