Kinetochores are large structures composed of hundreds of proteins that assemble onto centromeric DNA to form a microtubule-binding site that is essential for proper chromosomal segregation. The structure of budding-yeast kinetochore particles is now studied by EM and electron tomography, revealing a large central hub surrounded by multiple globular domains, and multiple attachment sites for microtubules.
