- nucleus breaks down - prophase
- chromosomes become visable as 'pair of chromotids'
- protein molecules (spindle, spindle fibre) extend
- chromotids will move to the centre of the spindle
- metaphase - chromotids is attached to the spindle fibre by the centrimere - chromotids are in the middle
- anaphase - fibre shortens splitting the chromotids apart and halves the centrimere
- telophase - formation of 2 nuclei, opposite ends of the cell
- cytokinesis - cell splits into 2
