Question

A scientist introduces the gene isolated from Bacillus thuringiensis in a plant to get a transgenic variety of that plant. What change in the characteristic of the plant is he aiming at?

• A. The transgenic plants will show resistance to nutrient scarcity.
• B. The transgenic plants will show resistance to boll worms.
• C. The transgenic plants will show resistance to water scarcity.
• D. The transgenic plants will show resistance to high salinity.

Answer 1

The correct option is B

The transgenic plants will show resistance to boll worms.

A classical example of a transgenic plant obtained by this method is the Bt cotton. It is a new variety of cotton in which a gene isolated from a bacterium, called Bacillus thuringiensis is newly introduced. This gene is responsible for producing a toxin which can kill the boll worms that attack the cotton plant.
