If Amphitelic attachment occur  Microtubules pull kinetochores; cohesins resist this pulling force. The resulting tension leads to the outer kinetochore component Ndc80 being pulled away from the protein kinase Aurora B

The Aurora protein kinase family members Aurora A and Aurora B and their associated regulatory factors sense kinetochores that are not under tension and sever these microtubule attachments
