If a cell needs to quit dividing, it enters a state where it stagnates to carry its normal cell activity. This is called as the _____ phase.
G0
The G0 phase is a period in the cell cycle in which cells exist in a quiescent state. G0 phase is viewed as either an extended G1 phase, where the cell is neither dividing nor preparing to divide, or a distinct quiescent stage that occurs outside of the cell cycle.
