- Mitosis
- Prophase
- DNA in chromosmes are packaged
- Chromosomes shorten and thicken
- Each chromosome has two chromatids
- The nuclear envelope breaks up
- Centrioles move to opposite ends of the cell to make the poles
- Metaphase
- Chromosmes come to the middle
- Centrioles organise microtubules into the spindle
- Chromosomes are attatched to the spindle at the centromere
- Anaphase
- Chromatids break away at the centromere and are pulled to the poles by the spindle
- Chromatids once seperated are now chromosomes
- Telophase
- Nuclear envelope reforms around each group of chromosomes at either end of the cell
- The chromosmes uncoil
- Interphase
- Followed by telophase in which Dna replicates again if the cell is going to divide again
- Prophase
