What is the cell cycle made up of? | Interphase, Mitosis, and Cytokinesis |
What's interphase? | *Cell grows to mature size. *Makes copy of DNA |
What's Mitosis? | Mitosis (cell division) has 4 phases |
What's prophase? | The chromatin in the nucleus condenses together to form chromosomes |

What's Anaphase? | Chromatids separate and move to opposite ends of cell |
What's Telophase? | New nuclear membrane forms around each group of chromosomes |
