The correct Answer is:
To solve the question regarding the incorrect statements about AIDS, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Statement I: "AIDS is caused by a retrovirus having two molecules of single-stranded RNA as its genome."** - **Analysis**: This statement is correct. AIDS is caused by the Human Immunodeficiency Virus (HIV), which is indeed a retrovirus. Retroviruses have two copies of single-stranded RNA as their genome. 2. **Statement II: "AIDS can be successfully treated using anti-retroviral drugs."** - **Analysis**: This statement is misleading. While anti-retroviral drugs can help manage HIV infection and improve the quality of life, they do not cure AIDS. Therefore, this statement is incorrect in the context of claiming it can be "successfully treated" as a complete cure. 3. **Statement III: "Macrophages act as a viral factory as it leads to the continuous production of new viral particles."** - **Analysis**: This statement is correct. HIV can infect macrophages, and these cells can indeed act as a reservoir for the virus, producing new viral particles continuously. 4. **Statement IV: "In AIDS, a decrease in B-lymphocyte count is seen."** - **Analysis**: This statement is incorrect. AIDS primarily affects T-lymphocytes (specifically CD4+ T cells), while B-lymphocyte counts are not significantly decreased in the same manner. The immune system is compromised, but the statement about B-lymphocytes is misleading. ### Conclusion: The incorrect statements regarding AIDS are: - **Statement II**: Misleading regarding treatment. - **Statement IV**: Incorrect about B-lymphocyte count. Thus, the answer to the question is that Statements II and IV are incorrect.

In the first biological applicativon of bucky ball , chemists at the University of Califorminaat San F Francisoc and Santa Barbra made a discovery in 1993 that could help I designing drugs to rtreat AIDS . The human immunodeficienrcy virus (HIV) that causes AIES reproduces by syntheising a long protein chain , which is cut into smaller segments by an enzymecalled HiV-proteases . ONe way to stop AIDS , then might be to inacivate the enzyme. when the chemists reacted a water-soluble derivative of bucky ball with HIV-protease , they found that itbinds to the portion of th enzyme that would ordinarily clareve the repreouctive protein , preventing the HIV virus from reproducing . Consequently the virus could no bnolgre infect the human cells they had frown in the laboratory . The buycky ball compound itself is not a suitable drug for use against AIDS because of potential side effects and delivery difficaultes , but it does provide a model for the development of such drugs Consider following statements about bucky ball : A , It is also called fullerene B: It is also called Buckminster fullerene C: Bucky tubes (made of fullerenes ) are several times stronger than steel wires D: Bucky ball is a plastic polymer Select correct statement (s) :
