DNA replication. Computer artwork of a DNA (deoxyribonucleic acid) molecule replicating. DNA is composed of two strands twisted into a double helix. Before replication the strands separate from each other. Each strand then acts as a template for the formation of a new DNA molecule. This is known as semiconservative replication. DNA contains sections called genes, which encode the body's genetic information.
