The decision for cell division is taken

Options

A. `G_(1)`
B. S
C. `G_(2)`
D. Not known

Answer

To answer the question "The decision for cell division is taken in," we need to analyze the phases of the cell cycle and identify where this decision occurs.

### Step-by-Step Solution:

1. **Understand the Cell Cycle Phases**: The cell cycle consists of two main phases: the mitotic phase and interphase. Interphase is further divided into three sub-phases: G1, S, and G2.

2. **Identify the G1 Phase**: The G1 phase occurs right after mitosis and before DNA replication begins. This phase is crucial as it prepares the cell for DNA synthesis.

3. **Functions of G1 Phase**: During the G1 phase, the cell undergoes various processes, including RNA synthesis and the replication of centrioles. This phase is considered an intermediate phase that sets the stage for DNA replication.

4. **Decision for Cell Division**: The decision for the cell to divide is primarily made during the G1 phase. This is when the cell assesses its environment and internal conditions to determine if it is ready to proceed with division.

5. **S Phase and G2 Phase**: In the S phase, DNA replication occurs, while in the G2 phase, there is intense synthesis of proteins and RNA. However, the actual decision to divide has already been made in the G1 phase.

6. **Conclusion**: Therefore, the correct answer to the question is that the decision for cell division is taken in the G1 phase.

### Final Answer:
The decision for cell division is taken in the G1 phase.
