| What Happens | Phase |
| Nuclear envelope dissolves, centrioles move to poles, DNA forms into chromosomes? | |
| DNA replicates? | |
| Daughter cells separate? | |
| Spindle fibers attach to centromeres, Chromosomes align on equatorial line? | |
| Cytoplasm duplicates, cell grows? | |
| Nuclear membrane forms, spindle fibers retract, daughter cells begin to invaginate? | |
| Spindle fibers that are attached to the centromeres shorten and separate the sister chromatids, spindle fibers that are not connected to a chromosome elongate to stretch the cell? | |
| Cell grows to the point that the DNA cannot control the whole cell effectively? | |
