Numerical: Cell Cycle Timing
Mediumbiology
A cell cycle totals 20 hours: G1=9h, S=6h, G2=3h. How long does M phase last?
Select the correct option:
Solution
Incorrect! Answer:
2 hours
- Interphase Components: The total time spent in interphase is the sum of G1,S, and G2 phases.
- Interphase Time=9 hrs(G1)+6 hrs(S)+3 hrs(G2)=18 hrs.
- Total Cycle: The whole cell cycle includes Interphase and the M (Mitotic) phase.
- Total Time=Interphase+M phase.
- Calculation:
- 20 hrs=18 hrs+M phase.
- M phase=2 hrs.
- Conclusion: The Mitotic phase lasts for 2 hours.
