Biology · Cell Cycle

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells

G₁ phase (Gap 1) – G₁ phase is the phase of the cell between mitosis and initiation of replication of the genetic material of the cell. During this phase, the cell is metabolically active and continues to grow without replicating its DNA.

G₂ phase is a period of rapid cell growth and protein synthesis during which the cell prepares itself for mitosis.

The G₀ phase is the phase in the cell cycle in which the cell is neither dividing nor preparing for division; hence it's in a resting phase. The cell enters this phase after it is done dividing or duplicating (mitosis).
