Genetic splicing is the process in which an organism's DNA is cut and another gene is added. It is used so single-celled organisms can produce certain products, such as insulin, and produces genetically altered organisms.
Gene splicing is normally done to prevent the growth of weeds and control diseases. It is also used for supplements and to improve crop strains. Gene splicing prevents and treats pain within the medical profession. Companies use the method to create certain enzymes that remove stains, and it is done to create lithium-ion batteries that are friendly to the environment. It is also used as a military tool to detect certain biological hazards such as anthrax.
