A detailed discussion of the kinetochore is beyond the scope of this article, but Figure 5 shows one model of how proteins might be organized within the kinetochore. Note the many CENP molecules ...

At the heart of the kinetochore is a specialized nucleosome that contains centromere protein (CENP)-A, a histone H3 homologue. Several inner kinetochore components (cyan and purple ovals ...

The kinetochore ensures the correct distribution ... In a first step, they can only recognize the centromere. "Using the model plant Arabidopsis thaliana, we have now been able to show that ...
