In this way is carried out treatment of children with immunodeficiency caused by adenosine deaminase defect in clinical trials are methods of gene-correction of inherited diseases such as familial hypercholesterolemia, hemophilia B, and some others.
It permits to create strong DNA that create strong resistance to diseases and allows the therapeutic development production of recombined insulin.
It allows the use plants and transgenic foods and genetically modified microorganisms to produce drugs and other vital products for men such as growth hormones, human insulin, vaccines and optimal food.
The use of DNA technology creates transgenic plants resistant to insects, fungi, bacteria and herbicides, and also provides higher nutritional content.
