Prophase: Centrosomes outside the nucleus have duplicated and move towards opposite sides of the cell. Spindle fibers appear. The nuclear envelope begins to fragment. Chromosomes condense and become visible under a light microscope.
Metaphase: The chromosomes are now at the equator of the cell.
Anaphase: Sister chromatids are pulled apart, becoming full-fledged chromosomes.
Telophase: The chromosomes arrive at the poles and then become indistinct chromatin. The spindles disappear as the nuclear envelope reassembles.
