WebCells duplicate DNA during interphase, usually shortly before entering either mitosis or meiosis (eukaryotic cells) or fission (prokaryotes). What are the 4 stages of the cell cycle? In eukaryotes, the cell cycle consists of four discrete phases: G 1 , S, G 2 , and M . WebThe 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. WebApr 8, 2024 · The biological function of meiosis is gamete formation (in gametic meiosis) or spore formation (in sporic meiosis), i.e., the production of cells qualified for sexual reproduction with half the quantity of chromosomes compared to the original cell.
