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.
Describe the process of DNA replication that occurs during the S phase of interphase. The DNA strand is completely copied by DNA polymerase enzymes, splitting it into two templates and forming complementary base pairs. This makes two exact copies of the parent DNA strand.
