AP Biology / Unit 4: Cell Communication and Cell Cycle
4.5 Cell Cycle
Notes
The cell cycle: interphase (G₁ growth, S DNA replication, G₂ prep) then mitosis (prophase, metaphase, anaphase, telophase) and cytokinesis.
- Mitosis gives two genetically identical daughter cells.
- Cells can exit to G₀ (non-dividing).
Practice
DNA is copied during:
S for synthesis.
Sister chromatids separate during:
They're pulled apart.
Mitosis produces cells that are:
Used for growth and repair.
