Microtubules from each centrosome connect to specialized regions in the centromere called kinetochores.
Microtubules tug on the kinetochores, moving the chromosomes back and forth, toward one pole, then the other.
The kinetochore is the protein structure on chromatids where the spindle fibers attach during cell division to pull sister chromatids apart during cell division.
Even the simplest kinetochores consist of more than 19 different proteins including a specialized histone which helps the kinetochore associate with DNA.

kinetochores are made up of kinetostoma which will together form as a unit called kinety.
