Nine doublets of them surround two singlets in flagella and cilia, and they form the spindle fibers that separate chromosomes during mitosis.
Mutations in the EFHC1 gene were recently found to disrupt their formation, which is inhibited by nocodazole in flow cytometry. Stathmin and Tektin interact with these structures, and they oscillate between "catastrophe" and "rescue" in a process called dynamic instability. The Gamma-TuRC complex assists with their formation. Drugs like Colchicine disrupt the dynamics of these structures. Dyein is a motor protein which moves toward the minus end of them, while kinesin moves toward the plus end. Nine doublets of them surround two singlets in flagella and cilia, and they form the spindle fibers that separate chromosomes during mitosis. For 10 points, name these structures composed of tubulin, which, along with microfilaments and intermediate filaments, make up the cytoskeleton.
