Vedclass · Answer

(A) $BT$ Cotton is a genetically modified organism $(GMO)$.It is created by introducing a specific gene from the soil bacterium $Bacillus$ $thuringiensis$ into the cotton plant.This bacterium produces a protein called the $Cry$ protein,which is toxic to certain insect larvae (like bollworms).When the insect ingests the plant tissue,the toxin is activated in its gut,leading to the death of the insect.Therefore,the correct statement is that a gene from a bacterium that produces a toxic substance has been introduced.
