The primary function of DNA polymerase is to
A) add nucleotides to the growing daughter strand.
B) seal nicks along the sugar-phosphate backbone of the daughter strand.
C) unwind the parent DNA double helix.
D) generate primers to initiate DNA synthesis.
E) prevent reassociation of the denatured parental DNA strands.

Question

DNA polymerase is the enzyme responsible for adding nucleotides to the growing daughter strand during DNA replication. It does not seal nicks along the sugar-phosphate backbone (ligase does that), unwind the parent DNA double helix (helicase does that), generate primers (primase does that), or prevent reassociation of denatured parental DNA strands (single-stranded binding proteins do that).
