Q.Which one of the following genetically engineered products helps the cells to resist viruses ?

Biotechnology's practical reach spans agriculture (transgenic Bt cotton, GM rice, tomato, tobacco, cauliflower, potato and banana bred for pest, stress and disease resistance), medicine (human insulin and blood proteins synthesised in E. coli, vaccines, therapeutic enzymes, antibiotics), industry and food (fermentation-derived dairy products and beverages, biochip-based biological computers), and the environment (single-cell protein from Spirulina, secondary metabolites, biofertilisers, biopesticides, biomass energy, biofuel, bioremediation and phytoremediation). Underpinning much of this are two core techniques - genetic engineering (deliberat …
