🎯 The Cell Cycle Overview
The cell cycle is the series of events that cells go through as they grow and divide. It has two main phases:
📚 Interphase (90% of cell cycle)
The 'busy' phase where the cell grows and prepares for division
- G1 (Gap 1): Cell grows and accumulates materials and energy
- S (Synthesis): DNA replication occurs - each chromosome is duplicated
- G2 (Gap 2): Cell continues to grow and proteins for division are made
🔄 M Phase (Mitosis + Cytokinesis)
The division phase where the nucleus and then the cell divide
- Mitosis: Nuclear division - chromosomes are distributed equally
- Cytokinesis: Cytoplasm division - cell splits into two
