If 5% of the cells are in mitosis in any given time and mitosis takes 1 hour to complete, what is the total cell cycle time for these cells?

A. 5 hours

B. 10 hours

C. 20 hours

D. 50 hours

How do you do questions like this one? I am totally blank on this.

I was able to cross off D because just by knowing the cell cycle, I know that is too long. Mitosis takes up a good portion if the time.


I know the stages of the cell cycle and what happens at each stage. Can someone go over the timings of each stage? How much time a cell spends at each of the stages?

Hi @vivatix

This looks like a proportion question. We can set up two ratios where the numerator represents mitosis in a given time and the denominator represents the total time.

So we would have:

5/100 = 1 hour mitosis/x total hours


Hope this helps. 🙂
