Mitotic spindle initiates during

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks when the mitotic spindle initiates during the stages of cell division: telophase, anaphase, prophase, or metaphase.

2. **Identifying the Stages of Mitosis**:
- **Prophase**: Chromatin condenses into visible chromosomes, and the mitotic spindle begins to form.
- **Metaphase**: Chromosomes align at the cell's equatorial plane, and the spindle fibers are fully formed and attached to the centromeres.
- **Anaphase**: Sister chromatids are pulled apart towards opposite poles of the cell.
- **Telophase**: Chromosomes arrive at the poles, and the cell begins to divide.

3. **Analyzing the Formation of the Mitotic Spindle**:
- The formation of the mitotic spindle is crucial for the movement of chromosomes during cell division.
- The spindle fibers are formed from microtubules and are responsible for separating the sister chromatids.

4. **Conclusion**: The mitotic spindle initiates during **prophase**, as this is when the chromatin condenses and the spindle fibers begin to form.

**Final Answer**: The mitotic spindle initiates during **prophase**.
