Which is the best example of genetic engineering? developing medical instruments to be used for treating cancer producing clothing made from natural plant fibers introducing a strain of bacteria in tomatoes that makes them insect resistant designing computer circuit boards that do not corrode

introducing a strain of bacteria in tomatoes that makes them insect resistant

Explanation:

Genetic engineering is a procedure in biotechnology which involves manipulation of the genome of the organism either by adding new genes or by deleting the disease causing genes. The genetic engineering is performed so as to improve the quality of organisms and preventing diseases and disorders.

Introducing a strain of bacteria in tomatoes that makes them insect resistant. is the correct option this is because of the fact that in this the bacterial genes will be introduced into the tomatoes. These bacterial genes will make the tomatoes resistant to insects. Here, the gene manipulation of tomato is involved hence, it is an example of genetic engineering.
