Crystals of Bt toxin produced by some bacteria do not kill the bacteria themselves because -
- Bacteria are resistant to the toxin
- Toxin is immature
- Toxin is inactive
- Bacteria encloses toxin in a special sac
The Correct Option is C
Solution and Explanation
In bacteria, the toxin is present in an inactive form, called prototoxin, which gets converted into active form when it enters the body of an insect.
Therefore, the correct option is (C): Toxin is inactive

Concepts Used:
Applications of Biotechnology
Biotechnology is the technology that utilizes biological systems, living organisms, or parts of this to develop or create different products.
For example, brewing and baking bread fall within the concept of biotechnology (use of yeast (= living organism) to produce the desired product).
Agriculture
Alternative to conventional farming: A possible solution is the use of genetically modified crops which is an alternative path to conventional farming.
Medicine
In the area of healthcare, recombinant DNA technological processes have made an immense impact which enables the mass production of safe and more effective therapeutic drugs.
Gene Therapy
A collection of methods that allows the correction of a gene defect that has been diagnosed in a child/embryo is called Gene Therapy.
CRISPR technology
For editing genomes, CRISPR is a simple yet powerful tool which allows researchers to easily alter DNA sequences and modify gene function.
