The cell cycle consists of four main phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). The G1 phase is characterized by cellular growth and preparation for DNA replication. The S phase is where DNA replication occurs, doubling the cellâs genetic material. The G2 phase involves further growth and preparation for mitosis, while the M phase encompasses the actual process of cell division, including mitosis and cytokinesis.
