Molecule tracking reveals mechanism of chromosome separation in dividing cells

University of Washington (UW) researchers are helping to write the operating manual for the nano-scale machine that separates chromosomes before cell division. The apparatus is called a spindle because it looks like a tiny wool-spinner with thin strands of microtubules or spindle fibres sticking out. The lengthening and shortening of microtubules is thought to help push and pull apart chromosome pairs...
