Question

The _______ state implies the exit of cells from the cell cycle

• A. S
• B. G1
• C. G2
• D. G0

Answer 1

Answer:

D. G0

• The quiescent stage is also known as the G₀ stage.

• The cells exiting from the cell cycle enter the G₀ stage after exiting the G₁ phase.

• The further division is stopped upon entering the inactive G₀ stage.

• Cells in the quiescent stage are metabolically active but they do not proliferate except when required.  

• For example, heart cells only divide occasionally to replace the cells.
