Question
___are made up of a family of related proteins having common structural and sequence features.
- Microtubules
- Microfilaments
- Intermediate filaments
- None of these
Hint:
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.
