The decision for cell division is taken

Options

A. `G_(1)`-phase
B. S-phase
C. `G_(2)`-phase
D. `G_(2)`-phase

Answer

**Step-by-Step Solution:**

1. **Understanding Cell Division**: Cell division is a crucial process for growth, development, and repair in organisms. It involves a series of phases that prepare the cell to divide.

2. **Identifying the Phases of the Cell Cycle**: The cell cycle consists of several phases, primarily divided into interphase and mitotic phase. Interphase is further divided into three key phases: G1, S, and G2.

3. **Focusing on Interphase**: Interphase is the phase where the cell prepares for division. It is during this phase that the cell makes critical decisions regarding its future.

4. **Examining the G1 Phase**: The G1 phase (Gap 1) is the first phase of interphase. It is an intermediate phase that occurs after the cell has completed mitosis and before DNA replication begins.

5. **Decision-Making in G1 Phase**: During the G1 phase, the cell assesses its environment and internal conditions to decide whether to proceed with the cell cycle. The options available to the cell include:
- Continuing to the S phase (where DNA replication occurs).
- Entering the G0 phase (a resting state where the cell is not actively preparing to divide).
- Undergoing differentiation (where the cell specializes and takes on a specific function).

6. **Conclusion**: The decision for cell division is primarily made during the G1 phase of interphase. This phase is critical as it determines whether the cell will continue to divide or enter a resting or differentiated state.

**Final Answer**: The decision for cell division is taken during the G1 phase of interphase.
