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.
DNA replication is semi-conservative because each helix that is created contains one strand from the helix from which it was copied. The replication of one helix results in two daughter helices each of which contains one of the original parental helical strands.
