Verified step by step guidance

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

Recall that sister chromatids are identical copies formed during DNA replication and are connected to ensure proper segregation during cell division.

Identify the specific region where sister chromatids are physically attached; this region is crucial for the attachment of spindle fibers during mitosis and meiosis.

Recognize that the centromere is the specialized DNA sequence and protein complex that holds sister chromatids together.

Differentiate the centromere from other chromosome regions such as the kinetochore (which assembles on the centromere), nucleolus (a nuclear structure), and telomeres (chromosome ends).
