Which phase is described as the holding phase of interphase where cells do not prepare for division?

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

Answer: (D)

The holding phase where cells aren’t preparing for division is G0. This is a quiescent state outside the active parts of the cell cycle, where cells remain metabolically functional but do not progress through G1, S, or G2 to mitosis. Some cells stay in G0 permanently (like many differentiated neurons), while others can re-enter the cycle if conditions signal division. In contrast, G1 is growth and a decision point to enter the cycle, S is DNA replication, and G2 is the final prep for mitosis. So G0 best fits the description of a non–dividing, resting phase.
