Question

Which of the following statements is incorrect about the G₀ phase?

• A. Mitosis occurs after the G₀ phase.
• B. Biocatalysts can be used to exit the G₀ phase.
• C. Cell metabolism occurs continuously in the G₀ phase.
• D. Cell volume goes on increasing during the G₀ phase.

Answer 1

The correct option is A

Mitosis occurs after the G₀ phase.

Cells which cannot divide further do not proceed beyond the G₁ phase and begin to differentiate into specific cell types. Such cells are said to be in the quiescent stage or G₀ phase. The cells remain metabolically active but do not proliferate. A cell at the G₁ phase commits whether to restart a new cell cycle or suspend the cell cycle to enter the G₀ phase.
