Bilateral Symmetry
Name the stages of Mitosis (4) and tell me briefly what occurs at each.
1. Prophase: chromosomes form identical strands (chromatids), coil tightly, and nuclear envelop begins to disappear
2. Metaphase: chromosomes move to central zone
3. Anaphase: chromatids pull apart and move to poles of cell (cleavage begins)
4. Telophase: nuclear envelope reforms, chromosomes start to uncoil, cleavage creates two cells
