Current Question (ID: 16161)

Question:

Read the following statements: (i) The main antibody produced as a result of allergic reaction is IgA. (ii) Modern-day lifestyle has resulted in lowering immunity and more sensitivity to allergens. (iii) Recombinant DNA technology has allowed the production of antigenic polypeptides of pathogens in bacteria or yeasts. (iv) Allergy is suppressed due to the release of histamine and serotonin. (v) The drugs like anti-histamines, adrenaline, and steroids quickly reduce the symptoms of allergy. Which of the above statements are incorrect?

Options:

1. (ii), (iii), (v)
2. (i), (iv)
3. (ii), (v)
4. (ii), (iii)

Solution:

The main antibody produced as a result of allergic reaction is IgE, not IgA. Allergy is not suppressed due to the release of histamine and serotonin; rather, these substances are involved in the allergic response.
