The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for an alternative name for "centromere." 2. **Analyzing the Options**: - **Option 1: Satellite**: This term refers to satellite chromosomes, which have additional constrictions known as secondary constrictions. This is not synonymous with centromere. - **Option 2: Primary Constriction**: This is the correct answer. The centromere is often referred to as the primary constriction of a chromosome because it is the region where the two sister chromatids are joined. - **Option 3: Kinetochore**: This term describes a protein structure that forms on the centromere during cell division, where spindle fibers attach. It is not another name for the centromere itself. - **Option 4: Secondary Constriction**: This term refers to constricted regions found at various points on a chromosome, but it does not refer to the centromere. 3. **Conclusion**: After analyzing all the options, the correct answer is that the centromere is also known as the **primary constriction**. **Final Answer**: The centromere is also known as the **primary constriction**. ---
