Which term describes a non-dividing state where cells temporarily stop dividing, often in response to unfavorable conditions?

• A. G0
• B. G1
• C. S phase
• D. Interphase

Answer: (A)

This term refers to a quiescent, non-dividing state in which a cell temporarily withdraws from the cell cycle when conditions are unfavorable. In this G0 state, the cell isn’t actively replicating DNA or preparing for division, though basic metabolism can continue. Cells can often re-enter the cycle later when conditions improve, starting again from the G1 phase. By contrast, G1 is a growth and preparation stage before DNA replication, S phase is when DNA is duplicated, and Interphase encompasses G1, S, and G2 before mitosis.
