Key differences, features, and comparative analysis of Phase and What happens.
| Phase | What happens | DNA |
|---|---|---|
| Gā (Gap 1) | Cell is metabolically active, grows continuously, makes RNA & proteins. No DNA replication. | 2C Ā· 2n |
| S (Synthesis) | DNA replication ā DNA amount doubles. In animal cells the centriole also duplicates in the cytoplasm. | 2Cā4C Ā· 2n |
| Gā (Gap 2) | Proteins (esp. tubulin for spindle) are synthesised; cell grows and gears up for mitosis. | 4C Ā· 2n |
