What happens to the molecule of double-stranded dna when it undergoes replication?

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.

Explanation:

DNA is a nucleic acid, one of the four major groups of biological macromolecules.DNA replication is semi-conservative. This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands.  

Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).DNA replication occurs through the help of several enzymes. These enzymes "unzip" DNA molecules by breaking the hydrogen bonds that hold the two strands together.

Each strand then serves as a template for a new complementary strand to be created. Complementary bases attach to one another (A-T and C-G).The primary enzyme involved in this is DNA polymerase which joins nucleotides to synthesize the new complementary strand. DNA polymerase also proofreads each new DNA strand to make sure that there are no errors.
