WEBKey points: DNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand. New DNA is made by enzymes called DNA polymerases, which require a template and a primer (starter) and synthesize DNA in the 5' to 3' direction.

WEBMar 17, 2022 · Figure \(\PageIndex{2}\): The semiconservative model of DNA replication is shown. Gray indicates the original DNA strands, and blue indicates newly synthesized DNA. During DNA replication, each of the two strands that make up the double helix serves as a template from which new strands are copied.

WEBAs synthesis proceeds, an enzyme removes the RNA primer, which is then replaced with DNA nucleotides, and the gaps between fragments are sealed by an enzyme called DNA ligase. The 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.
