This differential regulation ensures that the sisters remain attached only at the centromere just before anaphase, creating the tension necessary for proper alignment on the metaphase plate. It functions as the molecular handle that motor proteins and spindle microtubets grab onto during cell division.
Exploring Centromeric Sequences for Artificial Chromosomes in Biotechnology
Understanding their structure and function is essential for grasping how life maintains its continuity across generations. This constricted region is not defined solely by its location but by its unique chromatin structure, where standard DNA is tightly wrapped around histone proteins to form heterochromatin.
Without this critical hub, the orderly segregation of genetic material would be impossible. The Centromere: The Chromosome’s Central Hub Running parallel to the overall chromosome structure is the centromere, a specialized chromosomal region that acts as the anchor point for spindle fibers during mitosis and meiosis.

The centromere serves as the foundation for the kinetochore, a massive protein assembly that links the chromosome to the mitotic spindle. The Dynamic Lifecycle of Cohesion The cohesion between sister chromatids is established during the S phase of the cell cycle when DNA replication occurs.
