The cell cycle is a regular pattern of growth, DNA replication and cell division, that takes places in cells.
We break this pattern down into 4 main stages:
- Gap1 (G1) - cell growth and normal functions
- S Phase - DNA synthesis
- Gap 2 (G2) - additional growth
- Mitosis - this phase includes division of the cell nucleus (mitosis) and division of the cell cytoplasm (cytokinesis).
