Question

____ are composed of a protein, tubulin.

  1. Microfilaments
  2. Intermediate filaments
  3. Microtubules
  4. Flagella

hintHint:

Microtubules are cytoskeletons that have a tube-like structure.

The correct answer is: Microtubules


    • Microtubules are composed of a protein, tubulin.
    • The cytoskeleton is present inside the cytoplasm and is composed of three types of fiber, microtubules, microfibers, and intermediate fibers. The microtubules are the ones that are the thickest and are responsible for providing a proper framework to the cell but forming tubules. 
    • The microtubules are made up of tubulin protein. The alpha and beta tubulin, initially form a dimer. A large number of dimers like these join and they arrange themselves in the form of a chain. 13 of these chains then arranged cylindrically and take the shape of the tubule and thus, form the microtubules. 

    Other cytoskeletons are made up of other types of proteins.
