3
Q
Stage 1 Mitosis
A
Chromosomes begin to appear as threadlike structures
4
Q
Stage 2 Mitosis
A
The chromosomes ( now chromatids ) now appear as double threads joined at the centromere
5
Q
Stage 3 Mitosis
A
Pair of chromatids line up along the equator of the cell. Spindle fibres attach themselves to the centromere.
6
Q
Stage 4 Mitosis
A
The chromatids are pulled to opposite poles of the cell.
7
Q
Stage 5 Mitosis
A
Two new nuclei are formed.
8
Q
Stage 6 Mitosis
