Verified step by step guidance

Understand the structure of a chromosome: it consists of two sister chromatids joined together.

Recall that the point where the two sister chromatids are physically connected is crucial for chromosome stability and proper segregation during cell division.

Identify the protein disk that holds the sister chromatids together at this central region.

Recognize that this connecting region is called the centromere, which serves as the attachment site for spindle fibers during mitosis and meiosis.

Differentiate the centromere from other chromosome parts such as chromatin (the DNA-protein complex), telomeres (chromosome ends), and kinetochores (protein structures assembled on the centromere).
