Which of the following cytoskeletal elements principally com

Which of the following cytoskeletal elements principally compose the eukaryotic flagella?

A. Intermediate filaments

B. Microtubules

C. Actin filaments

Solution

Answer :

B) Microtubules e.g. - and -tubulin, dynein

Microtubules are hollow cylinders around 23 nm in width (lumen = roughly 15 nm in distance across), most ordinarily involving 13 protofilaments that, thus, are polymers of alpha and beta tubulin. They have an exceptionally dynamic conduct, restricting GTP for polymerization. They are normally composed by the centrosome.
