Question

First genetically modified plant commercially released in India is

• A. Golden rice
• B. Slow ripening tomato
• C. Bt brinjal
• D. Bt cotton

Answer 1

Answer: (D)

Bt cotton

Bt-cotton is the first genetically modified organism released in India. It is a genetically modified plant. Bt- gene is extracted from Bacillus thuringiensis which translates into cry protein which is antagonist to the several insecticides. The cry proteins attach themselves to specific locations on the cadherin-like proteins present on the epithelial cells of the midge and ion channels are formed which allow the flow of potassium. The excessive inflow of potassium causes death of the insects

So, the correct answer is 'Bt-cotton'
