Like myosins, kinesins and dyneins are both families of proteins. Which statement is true of all kinesins and dyneins?

Question

Quizplus · Accepted Answer

Both kinesins and dyneins are microtubule-dependent motors, meaning they use microtubules as tracks to move cargo within cells. While kinesins are generally plus-end-directed motors and dyneins are minus-end-directed motors, some isoforms of both families can move in the opposite direction. The motor activity of kinesins and dyneins resides in their heavy chains, not their light chains. Therefore, statement A is the only true statement of all kinesins and dyneins.
