- The process in which fragments of DNA from one or more different organisms are combined to form recombinant DNA.
A term used to refer to the process by which the DNA of an organism is cut and a gene, perhaps from another organism, is inserted. (See genetic engineering and recombinant DNA.) Gene splicing is often used in industry to allow single-celled organisms to produce useful products, such as human insulin. It is also used in the production of genetically modified organisms.
