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: DNA strand synthesized from 5' to 3' end. Starts at origin of replication which is a sequence that have a specific sequence of nucleotides which tells it where to begin. Proteins that initiate DNA replication recognize sequence, bind to it and separate the strands and open up replication bubble. Goes in both directions until the entire molecule is copied. At the end of each bubble is a replication fork, the region where the strands are being unwound.
