Cells in G 0 phase:
Options
- AExit the cell cycle
- BEnter the cell cycle
- CSuspend the cell cycle
- DTerminate the cell cycle
Correct answer
A. Exit the cell cycle
Step-by-step solution
The cells remain in an inert state in the G 0 phase of the cell cycle. Hence, G 0 can be either viewed as the distinct inert stage which occurs outside the cell cycle or as an extension to the G 1 phase, where cell neither divides nor prepares for it. Sometimes, G 0 is also referred to as “post-mitotic” state where cells in G 0 are in non-dividing phase in the outside of cell cycle. Some types of cells, such as nerve and heart muscle cells, become post-mitotic when they reach maturity (i.e., when they a
