Question

The genetically-modified (GM) brinjal in India has been developed for?

• A. Enhancing mineral content
• B. Insect-resistance
• C. Drought-resistance
• D. Enhancing shelf life

Answer 1

The correct option is B

Insect-resistance

The correct option is B.

Explanation of correct option:

1. The genetically modified (GM) brinjal in India is mainly developed to resist insects.
2. Crops like brinjal and cotton are genetically modified by introducing some foreign genes isolated from Bacillus thuringiensis.
3. These genes produce toxins that kill insects.

Explanation of incorrect options:

Option A:

1. Enhancement of mineral contents in plants improves the requirement of uptake of minerals from the soil.
2. The genetically modified brinjal plants in India do not enhance the mineral content.

Option C:

1. Drought-resistance in plants helps them survive environments with lack of water.
2. The genetically modified brinjal plants in India are not drought-resistant.

Option D:

1. Enhanced shelf life delays the withering of fruits and vegetables over time.
2. The genetically modified brinjal plants in India do not enhance the shelf life.

Final answer: The genetically-modified (GM) brinjal in India has been developed for insect resistance.
