Detailed explanation-1: -Bacillus thuringiensis crops: A few examples of transgenic plants are Bt cotton, Bt corn, Bt potato, and Bt tobacco. These plants are genetically engineered to possess endotoxin, which prevents the action of various pests that belong to the order: Lepidoptera, Coleoptera, Hymenoptera, Diptera, and Nematoda.

Detailed explanation-2: -Recombinant DNA technology has also proven important to the production of vaccines and protein therapies such as human insulin, interferon and human growth hormone. It is also used to produce clotting factors for treating haemophilia and in the development of gene therapy.

Detailed explanation-3: -In agriculture, recombinant DNA has improved plant growth by increasing nitrogen fixation efficiencies, by cloning bacterial genes, and inserting them into plant cells. Other plants have been engineered to be resistant to caterpillar, pests, and viruses by inserting resistant genes into plant genomes.

Detailed explanation-4: -Transgenic animals have been generated to understand normal physiological processes such as metabolism and blood cell production. Transgenic animals have been used to model human diseases and to develop new treatments. Transgenic crops have been produced that are resistant to infectious diseases and grow faster.
