Suppose, however, that during metaphase, this cell was treated with an inhibitor that blocks the function of the motor proteins in the kinetochore, but allows the kinetochore to remain attached to the spindle. the inhibitor has no effect on any other mitotic process, including the function of the nonkinetochore microtubules. consider these three questions concerning this animal cell that has been treated with the inhibitor: a. will this cell elongate during mitosis? (yes or no? )b. will the sister chromatids separate from each other? (yes or no? )c. will the chromosomes move to the poles of the cell? (yes or no? )
