DNA replicates by the semiconservative model of replication. This model states that during replication of double stranded DNA, the two strands separate and each separate strand is then used as a template to make a new strand.
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.
