The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the term that describes a constriction on a chromosome. 2. **Identifying the Options**: The options provided are: - Centromere - Centrosome - Centriole - Chromomere 3. **Analyzing Each Option**: - **Centromere**: This is the region on a chromosome where two sister chromatids are joined. It is characterized by a constriction and plays a crucial role during cell division. - **Centrosome**: This is an organelle that organizes microtubules and is involved in cell division. It does not refer to a constriction on a chromosome. - **Centriole**: This is a cylindrical organelle involved in cell division, specifically in the formation of spindle fibers. It is not related to the structure of chromosomes. - **Chromomere**: This refers to a bead-like structure formed by the coiling of DNA, but it does not specifically denote a constriction on a chromosome. 4. **Selecting the Correct Answer**: Based on the analysis, the correct answer is **Centromere**, as it is the specific term that describes the constriction on a chromosome. 5. **Conclusion**: Thus, the answer to the question "A constriction on the chromosome is" is **Centromere**. ---
