Question
(a) No bending would occur.
(b) Bending would occur exactly as diagrammed in Figure Q17-31A.
(c) Bending would occur, except that the right microtubule doublet would move down relative to the left one.
(d) The two microtubule doublets would slide away from each other.
Figure A shows how the movement of dynein causes the flagellum to bend. If instead of the normal situation, the polarity of the adjacent doublet of microtubules were to be reversed (see Figure B) what do you predict would happen? (a) No bending would occur. (b) Bending would occur exactly as diagrammed in Figure Q17-31A. (c) Bending would occur, except that the right microtubule doublet would move down relative to the left one. (d) The two microtubule doublets would slide away from each other.Explanation / Answer
Dynein moves from the + to - end. c) Bending would occur, except that the right microtubule doublet would move down relative to the left one.
