Read the following statements and choose the correct option: 1. Bt toxin is produced by a bacterium called Bacillus thuringiensis. 2. Bt toxin gene has been cloned from the virus and been expressed in plants to provide resistance to insects without the need for insecticides. 3. Production of pest resistant plants, can decrease the amount of pesticide used. 4. Examples are Bt cotton, Bt corn, rice, tomato, potato and

Step-by-step solution

Some of the applications of biotechnology in agriculture that you will study in detail are the production of pest resistant plants, which could decrease the amount of pesticide used. Bt toxin is produced by a bacterium called Bacillus thurengeneis. Bt toxin gene has been cloned from the bacteria and been expressed in plants to provide resistance to insects without the need for insecticides. Examples are Bt cotton, Bt corn, rice, tomato, potato and soyabean etc. Some strains of Bacillus thuringiensis produce protein
