  1. Question 1

    Q1. An HIV particle approaches a human T-lymphocyte. Which specific surface glycoprotein on the virus binds to the CD4 receptor of the host cell?

    • A) gp41
    • B) p24
    • C) gp120
    • D) Reverse transcriptase

    Answer: gp120

    Explanation: gp120 is the surface spike that binds CD4. gp41 is involved in fusion, and p24 is a core protein, not a surface receptor-binder.
