Which is the function of the enzyme DNA polymerase during replication?

A) bonds mRNA to original parent strand

B) bonds new nucleotides to parent strand

C) unwinds the replicated DNA strand

D) winds up the replicated DNA strand

The correct option is B) bonds new nucleotides to parent strand

Explanation:

DNA replication is a process by which DNA replicates by a semi-conservative method. The DNA double helix unwinds from the place where replication has to occur. Each strand of the DNA serves as a template strand for producing a daughter strand.

The DNA polymerase adds nucleotides complementary to each parent strand. In this way, a daughter strand is generated from the parent strands. This method of replication is termed as the semi-conservative method for DNA replication.
