genetic engineering

• • Genetic engineering is used to modify organisms to be resistant to diseases. Therefore, this prevents the occurrence of a disease in individual organisms. 
• • It is being used to develop better disease preventatives and treatments.
• •  utilising recombinant DNA technology to create transgenic crops or livestock resistant to diseases or pests, e.g. Bt cotton produces toxin to kills its pest allowing farmers to reduce the use of pesticides  
• • utilising recombinant DNA technology to create sterile mosquitoes to control and reduce the transmission of mosquito-borne diseases
