The first thing that happens is a replication structure binds to the DNA molecule. This is usually a signalling molecule or some type of protein. Next, this replication structure attracts DNA helicase enzymes which "unzip" the double stranded helix.

The DNA strands separate as the hydrogen bonds are broken by DNA helicase. Then complementary nucleotides line up next to the strands and DNA polymerase joins the nucleotides. DNA helicase unwinds a section of DNA at a time. This synthesises two double strands.
