Only one of them has a preferred assembly end accessory proteins B. Only one of them is capable of branching assembly. with the assistance of C. Only one of them has intrinsic structural polarity bound nucleotide D. Only one them is assembled from subunits with of E. Only one of them can associate with motor proteins Question 2 about cytoskeletal motor proteins? Which of the following is not a correct statement A. They are all ATPases. in only one direction along a cytoskeletal polymer B. Each of them is capable of movement cytoskeleton binding site C. Each of them has at least one globular head domain containing a microtubule. D. All microtubule associated motor proteins move toward the plus end of the Question 3 intermediate flaments cannot participate in following statements best describes why the generation A. They cannot the plasma membrane junctions B. They cannot interact with certain cell proteins C. They are found only in association with utilize motor D. They are not intrinsically and hence cannot polar assembly E. The cell is unable to control their Question 4 requires the involvement of myosin motor proteins?
