In which phase of the cell cycle centriole move towards opposite poles of the cell.

Options

A. Anaphase
B. Metaphase
C. Telophase
D. Prophase

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks in which phase of the cell cycle the centrioles move towards opposite poles of the cell.

2. **Identifying the Cell Cycle Phases**: The cell cycle consists of several phases: Interphase (G1, S, G2) and Mitotic Phase (Prophase, Metaphase, Anaphase, Telophase).

3. **Analyzing Each Phase**:
- **Anaphase**: In this phase, the sister chromatids are pulled apart towards opposite poles, but the centrioles are not specifically noted to be moving at this stage.
- **Metaphase**: During metaphase, chromosomes are aligned at the equator of the cell. There is no movement of centrioles towards the poles.
- **Telophase**: In telophase, the nuclear membrane reforms, and the cell begins to prepare for division, but the centrioles have already completed their movement by this stage.
- **Prophase**: This is the phase where chromatin condenses into visible chromosomes, and the centrioles begin to move towards opposite poles of the cell.

4. **Conclusion**: The correct answer is **Prophase**, as this is the phase where the centrioles are actively moving towards opposite poles in preparation for cell division.

**Final Answer**: Prophase
