Development of vaccine is difficult for AIDS because its gene
1 Undergoes mutation at rapid rate
2 Undergoes reverse transcription
3 Integrates into large number of host genes
4 Integrates its genome into that of helper cells
Explanation:
From the most fundamental standpoint, efforts to develop an HIV vaccine have been hampered by the genetic diversity of the virus itself. The replication cycle of HIV is not only fast (a little more than 24 hours) but is prone to frequent errors, churning out mutated copies of itself that recombine into new strains as the virus is passed from person to person. Developing a single vaccine able to eradicate over 60 dominant strains as well as the multitude of recombinant strainsand on a global level-becomes all the more challenging when conventional vaccines can only protect against a limited number of viral strains.

AIDS is due to
1 Reduction in number of helper \(T\) cells
2 Excessive production of interferons
3 Reduction in number of killer T cells
4 Autoimmunity
Explanation:
Helper T-lymphocytes play a great role in regulating the immune system. Destruction of helper-T-lymphocytes leads to the development of a immune deficiency which makes the patient susceptible to wide variety of infections.

Which of the below statements are correct? I. A widely used diagnostic test for AIDS is enzyme linked immuno-sorbent assay (ELISA). II. 1st December is celebrated as World AIDS Day.
1 Only I is correct
2 Only II is correct
3 Both are correct
4 None are correct
Explanation:
Statement I: A widely used diagnostic test for AIDS is enzyme linked immuno-sorbent assay (ELISA). Statement II: First recognized in 1988, World AIDS Day falls on December 1 each year.World AIDS Day is dedicated to spreading awareness of the AIDS pandemic spread by the spread of HIV infection, and to mourning those who have died of the disease.
