the identification of genes coding for useful traits and their introduction into other species of plants and animals ('transgenic species'). Genetic engineering offers the possibility of correcting genetic defects at source, or introducing new, desirable genetic characteristics that will stay with the subject and may be passed on to its successors. - manipulation of DNA to form a hybrid molecule, a new combination of non-homologous DNA (so-called recombinant DNA). The technique allows the bypassing of all the biological constraints to genetic exchange and mixing and may even permit the combination of genes from widely differing species. Genetic engineering developed in the early 1970s. [CUB
a scientific process that involves inserting genes from one species into another in an attempt to transfer a desired trait or character. Many of our foods such as soybeans and canola are genetically-engineered. Many people worry that we do not know enough about gene sciences to know what the results of genetic engineering will be. Genetic engineering reduces the natural diversity of nature creating a kind of monoculture in the gene world.
Any one of several techniques for the laboratory manipulation of genes, such as recombinant DNA technology. When reproductive cells are modified, this is called germ-line or heritable gene modification, and the changes made affect all descendants. When cells other than reproductive cells are modified, this is called somatic-cell or non-inheritable gene modification, and the changes affect only the individual.

See Biotechnology.
Group of new research techniques that manipulate the DNA (genetic material) of cells. The gene-splicing technique, which produces recombinant DNA, is a method of transporting selected genes from one species to another. For example, in this technique, the genes, which are actually portions of molecules of DNA, are removed from the donor (insect, plant, mammal or other organism) and spliced into the genetic material of a virus; then the virus is allowed to infect recipient bacteria. In this way the bacteria become recipients of both viral and foreign genetic material. When the virus replicates within the bacteria, large quantities of the foreign as well as viral material are made.
The use of various experimental techniques to produce DNA that contains new or modified genes or combinations of genes.
