Question

Which of the following products is not developed by the use of biotechnology?

• A. Bt cotton
• B. DNA vaccine
• C. Human protein enriched milk
• D. Basmati Rice

Answer 1

The Correct Option is D

Biotechnology is a field that involves the manipulation of organisms or biological systems to develop products or processes for specific uses. Let's analyze the options:

(1) Bt cotton: Bt cotton is developed using genetic engineering and biotechnology. It involves the introduction of a gene from the bacterium Bacillus thuringiensis, which makes the cotton resistant to pests.

(2) DNA vaccine: DNA vaccines are a product of biotechnology. They involve using a piece of the pathogen's DNA to stimulate an immune response in the body.

(3) Human protein-enriched milk: This product is also developed using biotechnology. Genetically modified cows are engineered to produce milk enriched with human proteins for medical use, such as for patients requiring specific proteins.

(4) Basmati Rice: Basmati rice is a traditional variety of rice and is not developed using biotechnology. It is a naturally occurring variety of rice, and while genetic modifications have been attempted in rice, Basmati rice itself is not a product of biotechnology.

Thus, the correct answer is (4) Basmati Rice, as it is not developed by the use of biotechnology.

Answer 2

Basmati rice is a traditional crop variety not developed by modern biotechnological methods. Bt cotton, DNA vaccines, and protein-enriched milk are developed through biotechnology.
