If mitotic division is restricted in `G_(1)` phase of cell, the condition is known as

Options

A. `G_(2)`-phase
B. S-phase
C. `G_(0)`-phase
D. M-phase

Answer

To solve the question "If mitotic division is restricted in G1 phase of cell, the condition is known as," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Cell Cycle**: The cell cycle consists of several phases, including G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). G1 is the first phase after cell division where the cell grows and prepares for DNA replication.

2. **Identify the Role of G1 Phase**: During the G1 phase, the cell assesses its environment and decides whether to proceed with division. If conditions are not favorable, the cell may halt its progression.

3. **Recognize the Outcome of Restricted Division**: If mitotic division is restricted during the G1 phase, the cell does not proceed to the S phase for DNA replication and ultimately to mitosis.

4. **Introduce the G0 Phase**: When a cell exits the cell cycle from the G1 phase and does not divide, it enters a resting or quiescent state known as the G0 phase. This phase is characterized by a lack of active division and can be temporary or permanent.

5. **Conclude the Answer**: Therefore, if mitotic division is restricted in the G1 phase, the condition is known as the G0 phase.

### Final Answer:
The condition is known as the G0 phase (or G0 stage).
