    Which of the following accurately describes the role of motor proteins during anaphase of mitosis?

    A

    Kinesins move chromosomes towards the minus ends of kinetochore microtubules, and dyneins move chromosomes towards the plus ends.

    B

    Dyneins move chromosomes towards the poles along kinetochore microtubules, while kinesins are involved in cytokinesis.

    C

    Kinesins move chromosomes towards the plus ends of kinetochore microtubules, while dyneins move the poles apart by acting on astral microtubules.

    D

    Both kinesins and dyneins move chromosomes towards the poles along kinetochore microtubules, with kinesins acting on the leading edge and dyneins on the trailing edge.
