- Chromosomes shorten and thicken as DNA is coiled.
- Each chromosome visible as 2 chromatids joined at centre.
- Nuclear envelope breaks into small pieces
- Centrioles organise fibrous proteins into the spindle
1 of 4
- Chromosomes held on spindle at middle of the cell
- Each chromosome attached to spindle on either side of its centromere (the circle separating the chromatids)
2 of 4
- Chromatids break apart from the centromere and line up at opposite ends of the cell by the spindle
3 of 4
- Nuclear envelopes reform around the chromatids that have reached the poles of the cell
- Each new nucleus has same number of chromosomes as original parent cell
- Nuclei genetically identical to each other
