WebJul 21, 2024 · 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’. DNA replication, like all biological polymerization processes, proceeds in three enzymatically catalyzed and coordinated steps: initiation, elongation and termination. For a cell to divide, it must first replicate its DNA. DNA replication is an all-or-none process; once replication begins, it proceeds to completion. Once replic…
