A new study has yielded insights into how chromosomes separate when a cell divides. Centromeres, located in the little pinched waist of each chromosome, control the movements that separate sister chromosomes when cells divide ensuring that each daughter cell inherits a complete copy of each chromosome -- and researchers have visualized how the parts of centromeres assemble themselves as human cells grow and divide.
