Which of the following statements is wrong for AIDS?
1 It is a blood-borne disease
2 It is transmitted chiefly by sexual contact
3 It is caused by HIV
4 Its causal agent belongs to retrovirus group
Explanation:
A HIV is transmitted primarily due to unsafe sexual relationship, contaminated blood transfusion hypodermic needles and from mother to child during pregnancy breast feeding. AIDS is caused by HIV (Human immunodeficiency Virus). HIV is a type of retrovirus and its genome is RNA.

ELISA is used to detect viruses where the key reagent is
1 DNA probe
2 RNAse
3 alkaline phosphatese
4 catalase
Explanation:
C Alkaline phosphates is found in the periplasmic space of E. coli bacteria. This enzyme is heat stable and has its maximum activity at high pH. ELISA are Enzyme-linked immunosorbent assay is a plate based assay technique designed for detecting and quantifying substances such as peptides, proteins, antibodies, antigens, and hormones. The commonly used enzymes in this technique are alkaline phosphates and peroxidase.

The spread of AIDS is promoted by
1 Homosexuality
2 Immoral way of life
3 Use of infected needles in blood transfusion
4 All of the above
Explanation:
D HIV is spread from the body fluids of an infected person, including blood, breast milk, semen and vaginal fluids. It is not spread by kisses, hugs or sharing food. It also spread from a mother to her baby. Use of infected needle in blood transfusion is self explanatory other than that immoral way of life refers to multiple, sexual partners homosexuals are at a greater risk of AIDS spread.

Which of the following statements is not true for retroviruses :-
1 Retroviruses carry gene for RNA-dependent DNA polymerase
2 The genetic material in mature retroviruses is RNA
3 Retroviruses are causative agents for certain kinds of cancer in man
4 DNA is not present at any stage in the life cycle of retroviruses.
Explanation:
D Retrovirus once it has infected a cell, it converts its RNA into viral DNA by reverse transcription. Retrovirus have RNA as a genetic material and hence they exhibit reverse transcription where by DNA is synthesized on RNA template. - They have reverse transcriptase as the enzyme. - This viral DNA is inserted into the DNA of the host cell where it starts replicating.

Identify the incorrect statement.
1 Pneumonia is a bacterial disease
2 Ringworm is a fungal disease
3 HIV is transmitted by mosquito bite
4 Cancer is a non-infectious disease
Explanation:
C HIV can't be transmitted through saliva, so it can't be transmitted through a mosquito's bite.
