How many hours is the inter-phase,the time in the cell cycle that is not devoted to mitosis?

1. 1 hour

2. 10 hours

3. 9 hours

4. 1/2 hour

5. 21 hourHow many hours is the inter-phase,the time in the cell cycle that is not devoted to mitosis?The answer is 21 hours, assuming that you are talking about a mammalian cell that takes approximately 24 hours to divide.



Interphase is 90% of the cycle. Most mammalian cells can complete both interphase and mitosis in 12-24 hours. You know that the answer has to be relatively big, because the cell spends most of the time in that stage. 21 hours is about 88% of the day, so I chose to assume we were talking about it on a 24 hour cycle.





Some bacteria cells can reproduce in 20 minutes or less, and some plant cells don't take as long as a mammalian cell.



Really, the answer depends on what type of cell it is.How many hours is the inter-phase,the time in the cell cycle that is not devoted to mitosis?interphase involve growth of various cell organelles and preparation of cell for next division. hence it takes up about 70-80% of cell cycle and lasts for 10-20 hoursHow many hours is the inter-phase,the time in the cell cycle that is not devoted to mitosis?21 hours
