At which stage of mitosis, the two daughter chromatids separate from each other, migrate towards the opposite poles and are now referred to as chromosomes of the future daughter nuclei?

Options

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

Explanation

To answer the question about the stage of mitosis when the two daughter chromatids separate and migrate towards opposite poles, we can break down the solution into the following 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 cell's equatorial plane (metaphase plate).
- **Anaphase**: This is the critical stage where the sister chromatids are pulled apart.
- **Telophase**: Chromosomes begin to de-condense, and the nuclear envelope re-forms around each set of chromosomes.

3. **Focusing on Anaphase**: During anaphase, the centromeres that hold the sister chromatids together divide. This division results in two separate daughter chromosomes.

4. **Movement of Chromosomes**: The newly formed daughter chromosomes are then pulled towards opposite poles of the cell due to the action of the spindle fibers. Each daughter chromosome now consists of one chromatid and is considered a complete chromosome.

5. **Conclusion**: The stage of mitosis where the two daughter chromatids separate and migrate towards opposite poles is called **anaphase**. At this point, they are referred to as chromosomes of the future daughter nuclei.

### Final Answer:
The correct stage of mitosis where the two daughter chromatids separate from each other and migrate towards opposite poles is **anaphase**.
