In this hypothetical situation, an inhibitor obstructs the function of motor proteins in the kinetochore while still allowing the kinetochore to stay attached to the spindle. The animal cells treated with this inhibitor can elongate during mitosis, leading to the separation of sister chromatids, but the chromosomes will remain still instead of moving to the poles of the cell. The only action the inhibitor affects is the motor protein function, which is responsible for the movement of chromosomes to the poles during cell mitosis.
