Question

An envelope surrounds the virus in

• A. HIV
• B. TMV
• C. T${}_2$
• D. Lambda phage

Answer 1

The correct option is A HIV

HIV is a lentivirus that causes AIDS. AIDS is a condition in humans in which progressive failure of the immune system allows life threatening opportunistic infections and cancers to thrive. Each virion of HIV comprises a viral envelope and a matrix which encloses the capsid. The capsid encloses two copies of the single stranded RNA genome and several enzymes. TMV, T2 and lambda phage does not contain envelope around the capsid. So the correct answer is 'HIV'.
