The centromere is A. a protein composed of 8 subunits that binds to DNA. B. an A-T-rich region of the chromosome which may be bound by kinetochores.

As a cell enters anaphase, cohesin is precipitously degraded, and the cell's sister chromatids separate to opposite poles of the spindle. Considering the many essential roles that centromeres play in mitosis, they are truly at the center of this process. Experiments over the past 30 years have shown that the centromere is far more than simply a primary constriction in a chromosome.
