Question

In a 2005 paper, Folker et al. propose that proteins like CLIP-170 “track” these structures via “motor-driven,” “surfing,” or “end-loading” mechanisms. The Ndc80-Nuf2 ends of rods in the Ndc80 complex associate with these structures and are organized by DASH/Dam1 complex rings, which encircle these structures. A four-headed protein slides antiparallel instances of these structures away from each other, shortening their overlap. (-5[1])(*) Gamma-TuRCs (-5[1])mimic a component of these structures in order to promote their assembly. (10[1]-5[1])These structures do not consist of (10[1])RNA, but the loss of a GTP cap from them promotes their (10[1])“catastrophe,” (10[1])causing them to exhibit dynamic instability. (10[1])Chromatid separation is primarily facilitated by the association of kinetochores with these structures. (10[1])For 10 points, name these structures along which dyneins and kinesins travel. ■END■ (10[4])

ANSWER: microtubules [accept spindles, spindle fibers, kinetochore microtubules, polar microtubules, or K-fibers] (The four-headed protein is kinesin-5.)
