<P> Microtubules are tubular polymers of tubulin that form part of the cytoskeleton that provides structure and shape to the cytoplasm of eukaryotic cells and some bacteria . The tubules can grow as long as 50 micrometres and are highly dynamic . The outer diameter of a microtubule is about 24 nm while the inner diameter is about 12 nm . They are formed by the polymerization of a dimer of two globular proteins , alpha and beta tubulin . </P>
