Cell growth occurs through a series of phases collectively known as the cell cycle. The cell cycle is divided into four main phases: G1 (gap 1), S (synthesis), G2 (gap 2), and M (mitosis). During the G1 phase, the cell grows and synthesizes various proteins needed for DNA replication. The S phase is characterized by the replication of DNA, while the G2 phase involves further growth and preparation for mitosis. Finally, during the M phase, the cell undergoes division to form two daughter cells.
