Interphase
Prophase
Events of Prophase
1.
- Nuclear membrane breaks down.
- Spindle forms.
- Sister chromatids line up at the center of the cell.
- The cell begins to pinch in two.
- Cytoplasm is divided into the two daughter cells.
- Chromosomes replicate in preparation for mitosis.
- Spindle forms.
- Sister chromatids (replicated chromosomes) condense.
- Sister chromatids line up at the center of the cell.
- The cell begins to pinch in two.
Metaphase
Events of Metaphase
- Chromosomes replicate in preparation for mitosis.
- Spindle forms.
- Sister chromatids (replicated chromosomes) condense.
- Sister chromatids line up at the center of the cell.
- The chromosomes begin to uncoil as the nuclear membrane reassembles around them.
- The cell begins to pinch in two.
- The sister chromatid pairs are pulled apart by the spindle fibers.
Anaphase
Events of Anaphase
- Nuclear membrane breaks down.
- Sister chromatids (replicated chromosomes) condense.
- Sister chromatids line up at the center of the cell.
- The chromosomes begin to uncoil as the nuclear membrane reassembles around them.
- The cell begins to pinch in two.
- The sister chromatid pairs are pulled apart by the spindle fibers.
- Cytoplasm is divided into the two daughter cells.
Telophase
Cytokinesis
Events of Cytokinesis
