What are the three types of the cytoskeleton?

Ans. The three types of cytoskeletons are microfilaments, intermediate filaments and microtubules. Microfilaments are the polymers of actin proteins. The intermediate filament’s size lies in between the microfilaments and microtubules. They mainly consist of keratin proteins. Microtubules are the largest and comprise alpha and beta-tubulin as monomers.
