describe the process of DNA replication and explain its significance

The process

Step 1: The DNA double helix is unwound by an enzyme.
Step 2: The DNA unzips forming two single strands
Step 3: Nucleotides are added to the single strands resulting in two identical strands of DNA

The two double stranded molecules are the chromatids.

The significance
