The eukaryotic cell cycle consists of four distinct phases: G1 phase, S phase (synthesis), G2 phase (collectively known as interphase), and M phase (mitosis and cytokinesis).
G1 – pre synthetic phase
S – synthetic phase
G2 phase- post-synthetic pre mitotic phase
M phase: Mitotic phase: Cells divide and produce new cells, which either directly re-enter next cycle or pass into non- proliferative G0 phase
G0phase – quiescent phase
