Vinblastine and taxol inhibit the assembly of these structures, and their depolymerization can be induced by colchicine. In Xenopus, the phosphorylation of the XMAP215 protein causes them to increase or decrease in size haphazardly, also called dynamic instability. They are nucleated at their minus ends at a gamma ring-complex found in their namesake "organizing centers." Kinesin and dyenin transport organelles and molecules along them and they are found in a 9+2 arrangement in cilia and flagella. For 10 points, identify these entities that are made up of tubulin and which serve to drive the cell apart via motor function during daughter cell
