  1. Question 1

    Q1. A genetic defect in keratin proteins leads to skin blistering when even minor pressure is applied. This highlights the role of which cytoskeletal fiber in providing mechanical strength?

    • A) Microtubules
    • B) Microfilaments
    • C) Intermediate filaments
    • D) Basal bodies

    Answer: Intermediate filaments

    Explanation: Intermediate filaments like keratin provide mechanical strength to skin. Microfilaments are tempting but they are involved in movement, not tensile strength.
