Which of the following is correct regarding AIDS causative agent HIV?
1 HIV is enveloped virus containing one molecule of single-stranded RNA and one molecule of reverse transcriptase
2 HIV is enveloped virus that contains two identical molecules of reverse transcriptase with ss-RNA
3 HIV is un-enveloped virus
4 HIV does not escape but attacks the acquired immune response
Explanation:
Retrovirus have an envelop consisting of a lipid bilayer derived from host cell membrane and projecting knob like glycoprotein spikes with pedicel formed of virus coded glycoprotein. This envelop encloses the RNA genome (single stranded RNA with two identical filaments and associated with a reverse transcriptase enzyme).

In full blown AIDS, opportunistic infections are caused by:
1 Mycobacterium
2 Toxoplasma
3 Viruses and fungi
4 All of these
Explanation:
People with AIDS may get life-threatening opportunistic infections, which are caused by viruses, bacteria, fungi and even parasites like Toxoplasma that usually don't make healthy people sick.

HIV enters human body and it enters into where RNA genome of virus replicates to form DNA
1 WBC
2 RBC
3 Macrophages
4 Erythrocytes
Explanation:
After getting into the body of the person, the virus enters into macrophages where RNA genome of the virus replicates to form viral DNA with the help of the enzyme reverse transcriptase.

In an infected human body the 'HIV factory' is
1 Sperm
2 Ova
3 Macrophages
4 \(\mathrm{RBC}\)
Explanation:
After getting into the body of the person, the virus enters into macrophages where RNA genome of the virus replicates to form viral DNA with the help of the enzyme reverse transcriptase. This viral DNA gets incorporated into host cell's DNA and directs the infected cells to produce virus particles. The macrophages continue to produce virus and in this way acts like a HIV factory.

Select the correct answer I. Time-lag between the infection and appearance of AIDS symptoms may vary from a few months to many years (usually 15-20 years). II. The HIV virus replicates to form viral DNA with the help of the enzyme reverse transcriptase.
1 Only I is correct
2 Only II is correct
3 Both are correct
4 None are correct
Explanation:
Incorrect statement I: There is always a time-lag between the infection and appearance of AIDS symptoms. This period may vary from a few months to many years (usually 5-10 years).
