Assumptions
•
The cell has 2n = 4: two pairs of chromosomes, one of each pair from each parent (red and blue).
•
Each stage’s length is for a typical human cell in culture with a 24 h cycle; mitosis takes about an hour of it.
•
Prometaphase begins when the nuclear envelope breaks down and the spindle catches the chromosomes.
