Question

Molecular probes are used for many genetic disorders like

• A. Duchenne muscular dystrophy
• B. Cystic fibrosis
• C. Tay-Sachs disease
• D. All of these.

Answer 1

Answer: (D)

All of these.

Molecular probes are the molecules which are used to study the property of other molecules or their structures. The choice of the probe depends upon the type of structure of the compound that needs to be studied for example to study the complementary base pairing of DNA or RNA the radioactively labelled probes are used.

To study genetic disorders, for example, many severe combined immunological deficiencies, cystic fibrosis or muscular dystrophy, probes are used. Probes tell about the neurological function of the gene and in general the normal function of the gene.

So, the correct option is 'All of these.'
