Question

___are made up of a family of related proteins having common structural and sequence features. ​

  1. Microtubules
  2. Microfilaments
  3. Intermediate filaments
  4. None of these

hintHint:

The family of related proteins is present in one of the types of the cytoskeleton.

The correct answer is: Intermediate filaments


    • Intermediate filaments are the ones that are made up of a family of related proteins having common structural and sequence features. ​
    • Intermediate filaments belong to the cytoskeleton present inside the cytoplasm known for providing proper shape and structure to the cells. 
    • Their size ranges between the microtubules and microfilaments and they are composed of a family of related proteins. The protein is usually known as flagellin. It arranges in the form of a filament and gives it the right structure. 
    • This property makes it highly advantageous to be a part of the flagella. 

    It is known that microfilament is composed of actin and microtubules are composed of tubulin protein.
