The answer is <span>DNA polymerases add nucleotides to the exposed base pairs according to base-pairing rules.
DNA polymerase performs the polymerization of DNA. It adds nucleotides to the new DNA strand according to the base-pairing rules. This means that adenine binds to thymine and guanine binds to cytosine. The DNA polymerase is important enzyme responsible for accurate DNA replication.
Choice 2 is incorrect because DNA does not contain uracil.
