Regulation of Chromosome Speeds in Mitosis [PDF]
Cellular and Molecular Bioengineering, 2013 When chromosome are being separated in preparation for cell division, their motions are slow (~16 nm/s) relative to the speed at which many motor enzymes can move their cellular cargoes (160-1000 nm/s and sometimes even faster) and at which microtubules (MTs) depolymerize (~200 nm/s).
