For successful cell replacement during tissue repair, the chromosome content of each daughter cell must be identical to that of the mother cell. Which stages of mitosis make sure that each daughter cell receives one chromatid from each chromatid pair?

Options

A. Prophase and metaphase
B. Metaphase and anaphase
C. Anaphase and telophase
D. Telophase and interphase

Answer

To solve the question regarding which stages of mitosis ensure that each daughter cell receives one chromatid from each chromatid pair, we can break down the process of mitosis into its key phases and identify their roles.

### Step-by-Step Solution:

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

2. **Interphase**: Before mitosis begins, the cell is in interphase, where DNA is replicated. Each chromosome consists of two sister chromatids, which are identical copies of the chromosome.

3. **Prophase**: During prophase, the chromatin condenses into visible chromosomes, and the mitotic spindle begins to form. However, the separation of chromatids has not yet occurred.

4. **Metaphase**: In metaphase, the chromosomes align at the cell's equatorial plane (metaphase plate). The spindle fibers attach to the centromeres of the sister chromatids. This alignment is crucial for ensuring that each daughter cell will receive one chromatid from each pair.

5. **Anaphase**: Anaphase is the stage where the sister chromatids are pulled apart by the spindle fibers and move toward opposite poles of the cell. This separation is critical because it ensures that each daughter cell will receive one copy of each chromatid.

6. **Telophase**: In telophase, the separated chromatids reach the poles, and the nuclear envelope begins to reform around each set of chromosomes. The cell is preparing to divide into two, but the actual separation of the cytoplasm occurs in cytokinesis, which is not part of mitosis itself.

### Conclusion:
The stages of mitosis that ensure each daughter cell receives one chromatid from each chromatid pair are **Metaphase** and **Anaphase**.
