Which motor protein moves toward the minus end of microtubules? Question 6Answer a. Kinesin. b. Myosin II. c. Dynein. d. Myosin V.
Added by Jordi P.
Step 1
- Kinesin generally moves toward the plus end of microtubules. - Dynein generally moves toward the minus end of microtubules. - Myosin II and Myosin V move along actin filaments, not microtubules. Show more…

The mechanochemical enzyme that can be found on the surfaces of cellular organelles where it mediates movement toward the plus end of microtubules is which of the following? a. Myosin (myosin II) b. Minimyosin (myosin I) c. Dynein d. Kinesin e. Filamin
Please answer all the parts a) Which family of microtubule motor proteins (kinesins or dyneins) is, structurally speaking, most similar to myosins? b) Which family of microtubule motor proteins (kinesins or dyneins) typically acts as a minus-end-directed motor protein (i.e., moves from the minus toward the plus end)? Which one acts as a plus-end-directed motor protein? c) What microtubule motor protein is crucial for the bending motion of flagella & cilia? d) Which part of Anaphase (Anaphase A or Anaphase B) is associated with the movement of chromosomes towards the spindle poles (MTOCs)? e) Which part of Anaphase (Anaphase A or Anaphase B) is associated with the movement the spindle poles (MTOCs) further apart from one another and closer to the plasma membrane?
