Living cells depend absolutely on microtubules that form a scaffolding for moving materials inside the cell. Microtubule fibers are hollow rods made of much smaller tubulin subunits that spontaneously assemble at one end of the rod, but exactly how they do this inside the crowded environment of living cells has been a mystery. Now researchers have uncovered the mechanism that puts these blocks in place.
