During animal cell division, a highly synchronized and tightly regulated dance of chromosomes takes place, ensuring the chromosomes split correctly into the two cells. Spindle fibers—complex machinery ...
The mitotic spindle consists of two spindle poles that nucleate microtubules from their minus-ends, and three classes of microtubules: kinetochore microtubules that attach to chromosomes, interpolar ...
During cell division, the pericentriolar matrix (PCM; blue lines) expands. In C. elegans, the main structural protein of the PCM is SPD-5, which, upon activation, binds to γ tubulin complexes (purple ...
