DNA Replication

DNA replication begins with the unzipping of the parent molecule as the hydrogen bonds between the base pairs are broken.
Once exposed, the sequence of bases on each of the separated strands serves as a template to guide the insertion of a complementary set of bases on the strand being synthesized.

Before a cell can reproduce, it must first replicate, or make a copy of its DNA. This structure can unzip down the middle and each side and can serve as a pattern or template for the other side called semi-conservative replication. However, DNA does not unzip entirely. It unzips in a small area called a replication fork, which then moves down the entire length of the molecule.
