"WebApr 21, 2016 · Symmetric dynein moves randomly around the initial position. Moreover, the directional motion becomes more obvious as an additional mass is attached to the linker of simulation dynein. Thus, the direction of the motion of dynein can be determined based on the shift in the CM (asymmetry) of dynein according to the proposed dynamic mechanism. " - Dynein moves in which direction
