Question

Find the most accurate description of ‘Bt Cotton’

• A. A variety of cotton that grows fast
• B. A genetically modified crop of cotton whose DNA has been altered by introducing an extra gene
• C. A variety of cotton that is immune to diseases.
• D. A genetically modified crop of cotton whose DNA has been designed in the lab.

Answer 1

The Correct Option is B

Bacillus thuringiensis (Bt) Cotton is a genetically modified variety of cotton that has been engineered to produce an insecticide to combat bollworm, a significant pest in cotton production. The DNA of Bt Cotton is specifically altered by introducing a gene from the bacterium Bacillus thuringiensis, which naturally produces a toxin harmful to certain insect larvae. This modification incorporates the insecticidal protein directly into the plant's tissues, providing inherent protection against pest attacks without the need for external insecticide applications.

Question	Find the most accurate description of ‘Bt Cotton’
Options	A variety of cotton that grows fast A genetically modified crop of cotton whose DNA has been altered by introducing an extra gene A variety of cotton that is immune to diseases. A genetically modified crop of cotton whose DNA has been designed in the lab.
Correct Answer	A genetically modified crop of cotton whose DNA has been altered by introducing an extra gene
Explanation	Bt Cotton is specifically created to incorporate a gene from naturally occurring soil bacterium Bacillus thuringiensis, which produces proteins toxic to certain insect larvae, thereby reducing the reliance on external pesticides and promoting pest resistance directly in the plant.
