What is the point at which a dna strand is unzipped so that it can form new complimentary strands?

a). polymerase
b). nuclease
c). replication fork
d). double helix

replication fork

Explanation:

DNA strand is unzipped to allow new complementary strands to be formed. The chains separate starting from one end through breakage of hydrogen bonds. This exposes the bases. Deoxyribonucleotides align themselves in a complementary way along the two chains. The process of replication occurs with the help of template strand and DNA polymerase enzyme that synthesizes the new strand.
