Webb13 mars 2024 · DNA replication is the process of copying the DNA in a cell so that there are two copies. This is done in preparation for cell division, or mitosis. Before a cell divides, the DNA must be copied so that there is a copy for each of the resulting daughter cells. First, the DNA unwinds and the two strands of the helix separate.
