Definition
noun
The technology entailing all processes of altering the genetic material of a cell to make it capable of performing the desired functions, such as producing novel substances.
Supplement
Genetic engineering covers all various experimental techniques that manipulate the genes of the organism. It uses recombinant DNA, molecular cloning and transformation. At present, it is applied in improving crop technology, manufacturing synthetic human insulin (using modified bacteria), production of erythropoietin (using Chinese hamster ovary cells), and production of new types of experimental mice for research (such as cancer mouse). It also has the potential of being used in humans by changing their appearance, intelligence, character and adaptability; however, there are ethical concerns and controversies it has to resolve before it can be widely accepted.
From the Web site of safe-food.org, genetic engineering is "a laboratory technique used by scientists to change the DNA of living organisms." Put another way, genetic engineering is "the alteration of genetic code using artificial means" (from www.globalchange.com). Genetic engineering is also called bio-engineering, gene-splicing, gene manipulation, etc. and the organisms that result from the practice are called genetically modified organisms (GMOs).
