The helix structure is unwound. This occurs at the cellular level leading to the multiplication of the genetic material. Replication includes steps initiation, elongation and termination. Replication follows several steps that involve multiple proteins called replication enzymes and rna.

Helicase brings about the procedure of strand separation, which leads to the formation of the replication fork. This exposes the two halves of the dna molecule and creates a replication fork , which moves down the duplicated dna as helicase continues to unwind it.
