Bt cotton is not (A) a GM plant (B) Insect resistant (C) a bacterial gene expressing system (D) resistant to all pesticides

A

A GM plant

B

Insect resistant

C

A bacterial gene expressing system

D

Resistant to all pesticides

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
Bt cotton is a genetically modified plant, genome of it is modified by inserting a foreign gene from a soil bacterium Bacillus thurengenesis.
This genetically modified plant cell produces .cry. protein. This protein when is ingested kill certain insects like, lepidopterancoleopterans and dipterans.
