DNA replication is the biological process in which two identical copies of DNA are produced from one original DNA molecule.
The steps involved in the process of DNA replication are as follows:
The first step in DNA replication is to ‘unzip’ the double-helix structure of the DNA molecule.
This is carried out by an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G). The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.
