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.
Thus DNA replication produces two identical, double helical molecules, enabling genetic information to be copied and passed on from a cell to its daughter cells and from a parent to its offspring. â¢ During replication, the two strand of a DNA double helix are pulled apart to form two Y-shaped replication forks.hus DNA replication produces two identical, double helical molecules, enabling genetic information to be copied and passed on from a cell to its daughter cells and from a parent to its offspring. â¢ During replication, the two strand of a DNA double helix are pulled apart to form two Y-shaped replication forks.
