Question

Name the state where never dividing cells of neurons and skeletal muscle are present?

• A. G$_0$
• B. G$_1$
• C. G$_2$
• D. M

Hint:

Cells that do not divide after differentiation (e.g., neurons, muscle cells) remain in the \textbf{G$_0$ phase}.

Answer 1

The Correct Option is A

Step 1: The cell cycle consists of phases G$_1$, S, G$_2$, and M.
Step 2: Some cells permanently stop dividing and exit the active cell cycle.
Step 3: These cells enter a resting or quiescent phase known as G$_0$ phase.
Step 4: Neurons and skeletal muscle cells are terminally differentiated and remain permanently in the G$_0$ phase.
