Bollgard I and II Transgenic Technologies

Bollgard I and Bollgard II are proprietary transgene technologies developed to produce genetically modified Bt cotton crops. They incorporate insecticidal crystal protein genes (Cry1Ac and Cry2Ab) from the soil bacterium Bacillus thuringiensis into cotton plants to provide built-in protection against lepidopteran pests like the cotton bollworm. > Bollgard technologies represent commercial applications of genetic engineering used to build pest resistance in transgenic cotton crops. Answer: (b).
