WebThe following points highlight the four major phases of the cell cycle. The phases are: 1. G 1 (gap1) phase 2. S (synthesis) phase 3. G 2 (gap 2) phase 4. M (mitosis) phase. Cell Cycle: Phase # 1. G 1 Phase: . The G 1 phase is set in immediately after the cell division. It is characterised by a change in the chromosome from the condensed mitotic state to … WebJul 30, 2024 · The first stage of interphase is called the G1 phase (first gap) where the cell is quite active at the biochemical level. The cell is accumulating the building blocks of chromosomal DNA and the associated proteins as well as accumulating sufficient energy reserves to complete the task of replicating each chromosome in the nucleus.
