Phases of the Cell Cycle/Mitosis

1. Interphase:
   • the largest phase
   • a. G1 (gap 1) – cell grow
   • b. S (synthesis) – DNA replicated
   • c. G2 (gap 2) – cell prepares to divide
2. Prophase:
   • cromatin condense into chromosomes
   • nucleolus dissapears
   • nuclear membrane dissolves and centromeres connect to spindle fibers
3. Metaphase:
   • chromosomes align at metaphase plate along the center of cell
   • they align due to opposite pull of centerosomes
4. Anaphase:
   • the proteins binding sister chromotids together break anddaughter chromosomes go to opposite ends of the cell
5. Telophase:
   • spindle fibers disappear
   • nucleolus reappears
   • nuclear membrane is formed
   • chromosomes → cromatin
6. Cytokinesis:
   • cell pinches apart by means of a contractile ring that tightens where the metaphase plate was
