WebIn the process of DNA replication, the DNA makes multiple copies of itself. It is a biological polymerisation, which proceeds in the sequence of initiation, elongation, and termination. It is an enzyme-catalysed reaction. DNA … WebJul 8, 2024 · The method by which the genome’s DNA is duplicated in cells is known as DNA replication. Before dividing, a cell must copy its whole genome so that each ensuing daughter cell has its full genome. Why does DNA Replicate? DNA is the genetic substance that gives each cell its identity.
