The process by which the DNA double helix is copied. If the strands are separated, each single strand can act as a template for copying the other strand. Polymerisation is the process by which monomer molecules are joined to form polymer chains.

The process by which polymer chains are allowed to grow along template macromolecules for the greater part of their lifetime. A template is any molecule that acts as a pattern for the synthesis of a new molecule, and polymerization is the process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or pol [..]
