Question

Carefully study the information below about the cell cycle of a particular multicellular eukaryotic organism.



Given the data, how long is the cell cycle for these cells?

It takes 3 hours for the nucleus to divide and 1 hour for the cytoplasm to divide.
After 8 hours, the cell will start dividing again.
It takes 2 hours for the cell to copy its genetic material.





A.
1 hour


B.
4 hours


C.
8 hours


D.
12 hours

Answer 1

please help

Answer 2

The division of the cytoplasm (cytokinesis) follows the division of the nucleus (mitosis), so I would say these two occur separately, which means mitosis and cytokinesis should take 4 hours total (3 for mitotic division, 1 for cytoplasmic).

The cell would then enter the gap (G1 and G2) and synthesis (S) phases, which apparently take 8 hours in total before division is initiated. The time it takes for DNA to replicate is included in these 8 hours (since it occurs during the S phase). I would say it takes a total of 12 hours (4 from the actual division stages and 8 from the G/S phases combined).
