Cell Biology 06: The Cytoskeleton Part II: Tubulin. These are notes from lecture 6 of Harvard Extensionâs Cell Biology course. Last week we covered microfilaments, which are made of actin. This week: microtubules, made of tubulin. Why, you ask, does the cytoskeleton need two separate systems? Consider that microfilaments are just chains of individual subunits, whereas microtubules are literally tubes (as weâll see shortly) â hollow cylinders with walls made of chains made of dimers.
