What is G0 (quiescent phase) of cell cycle?
Advertisements
उत्तर
- The G0 phase occurs when the cell cycle is inactivated because mitogens and substances high in energy are not available.
- At this stage, cells still have an active metabolism but stop proliferating, meaning they don't grow or differentiate unless the organism requires them to.
- For instance, chordate nerve and heart cells are always in the G0 phase.
