Prophase; failure of chromosome condensation
Metaphase; misalignment of chromosomes at the metaphase plate

Which of the following accurately describes the role of motor proteins during anaphase of mitosis?
Kinesins move chromosomes towards the minus ends of kinetochore microtubules, and dyneins move chromosomes towards the plus ends.

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