Math Fun and the cell cycle
A scientist observes 240 cells. 180 are in
interphase, 25 are in prophase, 24 are in
metaphase, 6 are in anaphase and 5 are
in telophase.
A complete cell cycle for this cell is 24 hours.
What is the average duration of mitosis?
A scientist observes 100 cells. 50 are in
interphase, 18 are in prophase, 19 are in
metaphase, 7 are in anaphase and 6 are in
telophase.
A complete cell cycle for this cell is 50 hours.
What is the average duration of mitosis?
