Question

Assuming that a normal human cell takes 720 minutes to complete one mitotic cycle, indicate the number of minutes that the cell spends in each stage of mitosis.

Answer 1

Interphase is the phase before it starts mitosis in which the cell grows and replicates both it’s DNA and organelles. This phase takes up 78% of the cell’s lifetime = 561.6 minutes

Prophase takes up around 14% of the cell’s life cycle = 102.8 minutes

Metaphase involves 4% of the total mitosis cycle so = 28.8 minutes

Anaphase is the shortest phase of mitosis, taking up only 0.8% of the cycle = 5.2 minutes

Telophase is the final phase of the mitosis cell cycle and lasts around 3% of the total time = 21.6 minutes
