• A. telomere
• B. centromere
• C. kinetochore
• D. chromatid

Answer: (B)

Verified step by step guidance

1. Understand the structure of a replicated chromosome: it consists of two identical sister chromatids joined together.
2. Recall that sister chromatids are connected at a specific region that plays a key role during cell division.
3. Identify the specialized region where sister chromatids are attached; this region is crucial for the proper segregation of chromosomes.
4. Recognize that the telomere is located at the ends of chromatids, not where they are joined.
5. Conclude that the correct term for the attachment point of sister chromatids is the centromere.
