Mitosis must be carefully regulated to ensure the normal distribution of chromosomes to the
daughter cells. A ring-shaped protein molecule known as cohesin attaches to the centromere
of a chromosome and holds sister chromatids together to prevent their premature separation.
Enzymes detach cohesin molecules from the centromere immediately before the sister
chromatids segregate.
