Scientific alteration of the structure of genetic material in a living organism. It involves the production and use of recombinant DNA and has been employed to create bacteria that synthesize insulin and other human proteins.
A process that alters the structure of an organism's genes, generally in an attempt to improve some aspect of the organism. Scientists have successfully used genetic engineering to protect some plants from particular kinds of viruses.
The manipulation of DNA to produce new types of organisms, usually by inserting or deleting genes.
Genetic engineering has been developed commercially, with uses such as producing human insulin or bacteria that will keep plants from freezing in a mild frost. It is also used to produce genetically modified organisms.
U.S. courts have ruled that the products of genetic engineering can be patented.
There is often controversy about the risk involved in releasing genetically engineered organisms into the environment.
The science of altering and cloning genes to produce a new trait in an organism or to make a biological substance, such as a protein or hormone. Genetic engineering mainly involves the creation of recombinant DNA, which is then inserted into the genetic material of a cell or virus.
