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 fibers sticking o...

New telomere discovery could help explain why cancer cells never stop dividing

Lausanne, Switzerland, October 4, 2007 A group working at the Swiss Institute for Experimental Cancer Research (ISREC) in collaboration with the University of Pavia has discovered that telomeres, the repeated DNA-protein complexes at the end of chromosomes that progressively shorten every time a ...
