Verified step by step guidance
1
Understand the structure of a chromosome: it consists of two sister chromatids joined together.
Recall that sister chromatids are identical copies of a chromosome formed during DNA replication.
Identify the specific region where sister chromatids are physically connected; this region is crucial for their proper segregation during cell division.
Know that the centromere is the constricted region of the chromosome where sister chromatids are attached.
Differentiate the centromere from other chromosome parts such as the kinetochore (protein complex on the centromere), chromatin (DNA and protein complex), and telomere (chromosome ends).
