WebThe process of DNA replication can be summarized as follows: DNA unwinds at the origin of replication. New bases are added to the complementary parental strands. The matching of free nucleotides to the parental strands is accomplished by an enzyme called DNA polymerase. Primers are removed, new DNA nucleotides are put in place of the primers ...
