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.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
