A given sample of somatic cell was treated with chemical X. it was found that chemical X inhibits chromatid separation . During somatic cell division process , the treated cell will reach which stage of division before being interrupted ?

Options

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

Answer

To solve the question regarding the effect of chemical X on somatic cell division, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Somatic Cell Division**: Somatic cells divide through a process called mitosis, which consists of several stages: Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.

2. **Identifying the Role of Chemical X**: The question states that chemical X inhibits chromatid separation. This means that the chemical is interfering with the process that allows sister chromatids to separate and move to opposite poles of the cell.

3. **Analyzing the Stages of Mitosis**:
- **Prophase**: Chromosomes condense and become visible, but chromatids are not yet separated.
- **Metaphase**: Chromosomes align at the metaphase plate, and spindle fibers attach to the centromeres of the chromatids.
- **Anaphase**: Sister chromatids are pulled apart towards opposite poles of the cell.
- **Telophase**: Chromatids reach the poles and begin to de-condense, preparing for cytokinesis.

4. **Determining Where the Process is Interrupted**: Since chemical X inhibits chromatid separation, it is most likely affecting the spindle fibers during the Metaphase stage. In Metaphase, the chromatids are aligned and ready for separation, but if the spindle fibers are inhibited, the separation cannot occur.

5. **Conclusion**: Therefore, the treated cell will reach the Metaphase stage of division before being interrupted by chemical X.

### Final Answer:
The treated cell will reach the **Metaphase** stage of division before being interrupted.
