They enter a state of dormancy and stop dividing.
B
They undergo apoptosis.
C
They immediately proceed to the S phase.
D
They continue to divide rapidly.
Verified step by step guidance1
Understand the cell cycle: The cell cycle consists of several phases, including G1, S, G2, and M. Cells may also enter a resting phase known as G0.
Define the G0 phase: The G0 phase is a state where cells are not actively preparing to divide. Cells in this phase are considered quiescent or dormant.
Consider the characteristics of cells in G0: Cells in the G0 phase do not proceed to the S phase, where DNA replication occurs, nor do they continue to divide rapidly.
Differentiate between dormancy and apoptosis: Apoptosis is programmed cell death, which is different from the dormancy seen in the G0 phase.
Conclude the behavior of cells in G0: Cells in the G0 phase enter a state of dormancy and stop dividing, rather than undergoing apoptosis or continuing to divide.
