Step1: Recall DNA replication basics

DNA replication is the process of making a copy of DNA. It starts with one molecule of DNA.

Step1: Understand semi - conservative replication

In DNA replication, each new DNA molecule consists of one old (template) strand and one new strand. So, one molecule of DNA replicates to form two molecules of DNA.

The double helix (original DNA) is unwound by helicase. The DNA template strands are exposed. Nucleotides pair with the bases on the DNA template strands. DNA polymerase then synthesizes (joins the nucleotides together) new strands of DNA, resulting in two double - helix DNA molecules.
