WebDNA replication, like all biological polymerization processes, proceeds in three enzymatically catalyzed and coordinated steps: initiation, elongation and termination. Initiation [ edit] Role of initiators for initiation of DNA replication. Formation of pre-replication complex. For a cell to divide, it must first replicate its DNA. [18] WebThere are three major steps involved in the process of DNA replication. The three steps are initiation elongation and termination, where first the parent DNA is separated and forms a single-stranded DNA structure, followed by replication with the help of enzymes.
