Detailed explanation-1: -Most GMO corn is created to resist insect pests or tolerate herbicides. Bacillus thuringiensis (Bt) corn is a GMO corn that produces proteins that are toxic to certain insect pests but not to humans, pets, livestock, or other animals.
Detailed explanation-2: -Bt maize/ Bt corn is a variant of maize that has been genetically altered to express one or more proteins from the bacterium Bacillus thuringiensis including Delta endotoxins. The protein is poisonous to certain insect pests.
Detailed explanation-3: -Agricultural biotechnology has been used to protect crops from devastating diseases. The papaya ringspot virus threatened to derail the Hawaiian papaya industry until papayas resistant to the disease were developed through genetic engineering. This saved the U.S. papaya industry.
Detailed explanation-4: -With genetic engineering, however, any gene from any organism can be transferred to a different organism. Thus, that allows a snippet of DNA that codes for an insecticidal protein from a bacterium, such as Bacillus thuringiensis (Bt), to be transferred into a corn or cotton plant.
