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 -> DNA. DNA -> RNA. Replication is the process in which a cell makes an exact copy of its own DNA (copy DNA -> DNA). Replication occurs in the S-fase in preparation to cell division during which the genetic information for the synthesis of proteins is transfered from the mothercell to the daughtercell.
