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 packaged into single-strand chromosomes are replicated (replication allows for each cell created by cell division to have the same genetic make-up); X shape is formed; once DNA replication is complete the cell contains twice its normal number of chromosoms and becomes ready to enter Growth 2 (G2)
