During mitosis, microtubule-organizing centers assemble the spindle fibers that separate the copying chromosomes of DNA. Researchers are now trying to decipher their molecular architecture. Integrative structure model of the yeast spindle pole body core, showing the proteins: Cnm67 (green), Spc42 (blue), Spc110 (red), Spc29 (purple) and Cmd1 (yellow).
