WebThe cell cycle is the sequence of events whereby a cell replicates its chromosomes and partitions the identical sister chromatids to two separate nuclear compartments (Morgan 2007).In eukaryotic cells, the phases of DNA synthesis (S phase) and mitosis (M phase) are temporally distinct and separated by gap phases (G1 – unreplicated chromosomes, and … Web1 mrt. 2024 · The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. The S phase only begins when the cell has passed ...
