Production of Recombinant Protein
Organisms such as bacteria which contained clone gene from other sources can lead to production of protein product with cloned genes. This called the recombinant protein. But, it is difficult to produce recombinant protein from the organisms in large quantity due to the complexity of gene express.

Transgenic Animal

Animal which have been inserted cloned genes generate transgenic animal and also termed genetically modified organisms. Transgenic animal is more profitable as animal can engineered to give more advantages in economic purpose. For example, cow can be engineered to produce more milk or quickly mature to earn profit as no need to feed more. The left picture shown GloFish, genetic modified fluorescent fish.

Gene therapy involve transferring a functional gene to cells to correct genetic disorder or acquired disease. Gene therapy was relatively limited success and not very efficient as only partial of the symptoms of disease being treated. The picture shown the example of process of gene therapy .

Medical utility
By introducing the gene which code for vitamin, hormones and antibiotics into the host cell normally is bacteria along with vector allow that host cell produce such substances.
Friendly insecticide
Bacillus thuringiensis able produce toxic to kill insect larvae pests. The Bt gene is introduce into crop cause the crop able to produce toxic kill the pests. There is 80000 times more toxic than typical chemical insecticide. This actually is the example of transgenic plant.
