  1. Question 1

    Q1. Hepatitis C often goes undetected for years because it avoids immediate immune destruction. What is a primary mechanism for its high rate of chronic infection?

    • A) Integration into the host genome
    • B) Destruction of all T-cells
    • C) Production of thick protective capsules
    • D) Frequent mutation of surface antigens

    Answer: Frequent mutation of surface antigens

    Explanation: Hepatitis C has a high mutation rate, leading to antigenic variation that evades the immune system. It does not integrate into host DNA like HIV.
