Question

What best describes the cell in the G₀ phase? They

• A. are metabolically inactive
• B. cannot divide forever
• C. can re-enter G₁ phase
• D. both 1 and 3 are correct

Answer 1

The correct option is C

can re-enter G₁ phase

The correct option is C.

Explanation of the correct option:

1. G₀ is the stage in a cell cycle in which neither the cell is actively dividing or preparing itself for a division.
2. It occurs after the G₁ phase of the interphase of the cell cycle.
3. It is also an inactive or a dormant stage, known as the quiescent stage, where cells are metabolically active and perform their normal routine functions in the body but do not further divide.
4. The division will occur only when required by the organism.

Explanation of the incorrect option:

Option A:

The cells in G₀ phase are metabolically active.

Option B:

The cells in G₀ phase can divide forever.

Hence, the final answer is that the cell in G₀ phase can re-enter the G₁ phase.
