To produce Bt cotton, the gene responsible for toxin production is isolated from Bacillus thuringiensis and integrated with the gene of the cotton plant.

Gene from Bacillus thuringiensis is introduced into soybean.

Write the following statements are True of false: Gene from Bacillus thuringiensis is introduced into cotton.

Where is 'cry gene' isolated from?

Diseases in humans can be prevented by administration of vaccines. Vaccines contain inactivated, killed / weakened pathogens that can be used as antigens to provide either permanent or temporary immunity against a specific pathogen or disease. Conventional methods of vaccine preparation include the use of completely or partially killed pathogens. These vaccines however posed a risk of causing disease in case of some persons. Biotechnological techniques provide alternative antigenic genes isolated in the laboratory that can be used to make pure forms of proteins that can be used as antigens to activate the immune system. Recent developments in this field include production of edible vaccines like transgenic potatoes. Consumption of raw potatoes is speculated to develop immunity against the pathogen. These edible vaccines are produced by inserting genes isolated from specific pathogens to produce the antigen in the plants. Based on the given paragraph answer the following questions. Why are vaccines produced using biotechnology safer than conventional vaccines?
