Name the stage of mitosis in which chromosomes are arranged on the equator of spindle

Options

A. Anaphase
B. Metaphase
C. Late prophase
D. S phase

Answer

To answer the question "Name the stage of mitosis in which chromosomes are arranged on the equator of spindle," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mitosis**: Mitosis is the process of cell division that results in two genetically identical daughter cells. It consists of several stages: prophase, metaphase, anaphase, and telophase.

2. **Identifying the Stages**:
- **Prophase**: Chromosomes condense and become visible; the nuclear envelope begins to break down.
- **Metaphase**: Chromosomes align at the equatorial plane of the cell, known as the metaphase plate.
- **Anaphase**: Sister chromatids are pulled apart towards opposite poles of the cell.
- **Telophase**: Chromatids reach the poles, and the nuclear envelope re-forms around each set of chromosomes.

3. **Focusing on the Question**: The question specifically asks for the stage where chromosomes are arranged on the equator of the spindle.

4. **Analyzing the Options**:
- **Option a: Anaphase** - This is when chromatids are separated and moving apart, not aligned at the equator.
- **Option b: Metaphase** - This is the stage where chromosomes are lined up at the equator of the spindle.
- **Option c: Late Prophase** - This is before the chromosomes have fully aligned.
- **Option d: S Phase** - This is the phase of DNA synthesis, not related to mitosis.

5. **Conclusion**: The correct answer is **Metaphase**, as this is the stage where chromosomes are arranged along the equator of the spindle.

### Final Answer:
The stage of mitosis in which chromosomes are arranged on the equator of the spindle is **Metaphase**.
