Question

Quizplus · Accepted Answer

Intermediate filaments can be composed of the protein vimentin. They are typically about 10 nm in diameter, not 70 nm, and are not composed of alpha and beta tubulin, which are components of microtubules. They are also not solely responsible for cell shape, as microtubules and actin filaments also play roles in maintaining cell structure.
