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

In order to determine which product is not developed using biotechnology, let's analyze the given options:

• Bt cotton: This is developed using biotechnology. It is a genetically modified organism (GMO) created by inserting genes from the bacterium Bacillus thuringiensis into cotton. This provides the plant resistance to certain pests.
• DNA vaccine: These are developed using biotechnology as they involve the use of DNA to generate an immune response. It involves the insertion of genetic material encoding an antigen to stimulate the body's immune system.
• Human protein enriched milk: Biotechnological techniques are used to create milk enriched with specific human proteins, like lactoferrin, that provide additional health benefits.
• Basmati Rice: This is a traditional variety of rice and is not typically developed using biotechnological methods. Although rice breeding can involve some technological interventions, Basmati is generally cultivated through selective breeding without the use of genetic engineering.

Conclusion: The product not developed by biotechnology is Basmati Rice.

Answer 2

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.
