Question

Which of the following is not a genetically modified crop plant ?

• A. Golden rice
• B. Flavr savr tomato
• C. Bt-corn
• D. Basmati rice

Answer 1

Answer:

D. Basmati rice

• Golden rice: This is a genetically modified variety of rice developed to produce beta-carotene, a precursor of vitamin A, giving it a golden color. It was created to address vitamin A deficiency in developing countries.

• Flavr Savr tomato: This was one of the first commercially grown genetically modified foods. It was engineered to have a longer shelf life by delaying the ripening process.

• Bt-corn: This is corn that has been genetically modified to express genes from the bacterium Bacillus thuringiensis (Bt), which produces proteins toxic to certain insect pests, providing the plant with built-in insect resistance.

• Basmati rice: This is a traditional, naturally occurring variety of long-grain rice grown in the Indian subcontinent. It has not been genetically modified through biotechnology but has been developed through conventional breeding techniques over centuries. Its distinctive aroma and flavor are natural characteristics.
