Cell Biology Interview Question:

Of which substance are microfilaments made? What are the properties of these elements that give motility to cells?

Microfilaments are made of actin (a protein). The contractile association of actin with myosin and other cytoplasmic proteins give to microfilaments the ability to promote cell movement.
