Cell Cycle
• Interphase – where a cell spends the majority of its life (over 90%)
![Page 11: Intro to the cell cycle & mitosis 2011. Intro to the Cell Cycle & cell reproduction 1.Read pages 180-182 Define the following terms: –Chromatin –Chromosomes.](https://reader035.fdocuments.in/reader035/viewer/2022070410/56649ea65503460f94ba92d6/html5/thumbnails/11.jpg)
5 Phases of the cell cycle
1. First growth (G1) phase cell grows rapidly and carries out its routine functions.
2. Synthesis (S) phase A cell’s DNA is copied
3. Second growth (G2) phase prepares for the nucleus to divide.
4. Mitosis the nucleus of a cell is divided into two
5. Cytokinesis the cytoplasm divides
