Answer & explanation
Correct answer: option 3
The correct answer is Option (3) -A-1,B-4,C-2,D-3
Column I Column II
A. Bt tobacco 1. Meloidogyne incognita
B. Humulin 4. Diabetes
C. Probe 2. A single-stranded DNA or RNA tagged with a radioactive molecule
D. ELISA 3. Diagnostic test
Explanation:
A. Bt tobacco - Meloidogyne incognita: Bt tobacco refers to tobacco plants that have been genetically modified to express a protein derived from the bacterium Bacillus thuringiensis (Bt), which provides resistance against pests like Meloidogyne incognita, a species of root-knot nematode.
B. Humulin - Diabetes: Humulin is a brand name for a type of human insulin used in the treatment of diabetes. It is produced through recombinant DNA technology.
C. Probe - A single-stranded DNA or RNA tagged with a radioactive molecule: In molecular biology, a probe is a labeled single-stranded DNA or RNA molecule used to detect the presence of a complementary target sequence in a sample. The radioactive tag is often used for detection purposes.
D. ELISA - Diagnostic test: Enzyme-Linked Immunosorbent Assay (ELISA) is a diagnostic test used to detect the presence of antibodies or antigens in a sample. It is widely used in medical and research settings for various purposes, including disease diagnosis.
