Hello,
The correct pair from above options is
3 helicase- unwind the DNA helix
Helicases are the enzymes present in living organisms that are used to separate DNA strands from double helix using energy from the hydrolysis of ATP. They are motor proteins that move directionally along nucleic acid phosphodiester bond to separate annealed strands.
