Question

Which of the following motor proteins function in anaphase B?

A. Kinesin-5 on interpolar microtubules and dynein on kinetochore microtubules.

B. Kinesin-13 on kinetochore microtubules and dynein on astral microtubules.

C. Kinesins 4 and 10 on interpolar and astral microtubules and dynein on kinetochore microtubules.

D. Kinesin-5 on interpolar microtubules and kinesins 4 and 10 on interpolar and astral microtubules.

E. Kinesin-5 on interpolar microtubules and dynein on astral microtubules.

What I think the answer is: E

Explanation / Answer

Answer - E. Kinesin-5 on interpolar microtubules and dynein on astral microtubules.

Plus end directed kinesin-5 & dynein push/pull poles apart and interpolar microtubules slide past each other and astral microtubules pull the poles apart.

Kinesin 4 and 10 function during prometaphase to promote center chromosomes on the metaphase plate.
