Write the phases of cell cycle.

The cell cycle consists of interphase and cell dividing phase. Three stages of cell cycle are called G₁ phase, S phase and G₂ phase. The resting phase or stage between two mitotic divisions is called interphase. There is no division in interphase but the volume of nuclear and cytoplasmic substances increases. G₁ phase is post mitotic gap period. S phase is synthetic phase. G₂ phase is called premitotic gap phase.
