Explain the structural composition and functions of microtubules, actin filaments, and intermediate filaments.
Added by Sara E.
Step 1
Microtubules are cylindrical, hollow tubes formed by the polymerization of α-tubulin and β-tubulin protein dimers. These tubulin dimers arrange themselves in a head-to-tail fashion to create linear protofilaments, typically 13 of which align side-by-side to form Show more…
