WebThe cell division process occurs as an orderly progression through four different stages, known collectively as the 'cell cycle'. Many of the abnormal traits of cancer cells are due to defects in genes that control cell division. The Cell Cycle. The cell cycle consists of four stages: G1, S, G2, and M. WebThe cell division stage is relatively short compared with interphase and is divided into the four phases of mitosis—prophase, metaphase, anaphase, and telophase—and …
