2. Melamine is commonly misused as a sugar adulterant.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: a
Justification:
-
Melamine is an organic base chemical most commonly found in the form of white crystals rich in nitrogen.
-
It is widely used in plastics, adhesives, countertops, dishware, and whiteboards.
-
To increase milk volume, water is added, as a result of this dilution the milk has a lower protein concentration.
-
Companies normally check the protein level through a test measuring nitrogen content.
-
The addition of melamine increases the nitrogen content of the milk and therefore its apparent protein content.
-
Melamine poisoning can lead to kidney-related diseases and also kidney failure.
2. HAMPIONS Portal is associated with
(a) Micro, Small and Medium Enterprises
(b) Women and Child Development
(c) Agriculture
(d) Higher Education

(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: c
Justification:
-
The enzyme-linked immunosorbent assay (ELISA) is a commonly used analytical biochemistry assay, first described by Engvall and Perlmann in 1971.
-
ELISA has been used as a diagnostic tool in medicine, plant pathology, and biotechnology, as well as a quality control check in various industries.
-
In the simplest form of an ELISA, antigens from the sample are attached to a surface.
-
Then, a matching antibody is applied over the surface so it can bind to the antigen.
-
This antibody is linked to an enzyme, and in the final step, a substance containing the enzyme’s substrate is added.
-
The subsequent reaction produces a detectable signal, most commonly a color change.
-
Because the ELISA can be performed to evaluate either the presence of antigen or the presence of antibody in a sample, it is a useful tool for determining serum antibody concentrations such as with the HIV test or West Nile virus.
-
It has also found applications in the food industry in detecting potential food allergens, such as milk, peanuts, walnuts, almonds, and eggs and as serological blood test for coeliac disease.
-
ELISA test is also used to detect various kind of diseases, such as dengue, malaria, Chagas disease, Johne’s disease.
