Following statements are regarding to the microtubules.

A. Tubulin is the major structural component of microtubules

B. Microtubule-associated proteins (MAPs) associate with tubulin and help mediate the assembly, dynamics, and function of microtubules.

C. Free tubulin exists as a dimer in which the α-subunit contains a trapped and hydrolyzable GTP and theβ-subunit binds an exchangeable and nonhydrolyzable GTP

D. All microtubules are nucleated from microtubule-organizing centers (MTOCs), and many remain anchored with their (−) ends there. Thus the end away from the MTOC is always the (+) end.
