Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms .
Genetic engineering techniques allow the modification of animal and plant genomes. Techniques have been devised to insert, delete, and modify DNA at multiple levels, ranging from a specific base pair in a specific gene to entire genes.

A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques.The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". [1]
Genetic engineering is a type of intentional genetic modification, which uses biotechnology to alter an organism's genome. [ citation needed ] According to World Health Organization (WHO), genetically modified organisms are defined as "Organisms (i.e. plants, animals or microorganisms) in which the genetic material (DNA) has been altered in a ...
Most focus on severe genetic disorders, including immunodeficiencies, haemophilia, thalassaemia, and cystic fibrosis. Such single gene disorders are good candidates for somatic cell therapy. The complete correction of a genetic disorder or the replacement of multiple genes is not yet possible. Only a few of the trials are in the advanced stages.
Genetic engineering is the direct manipulation of an organism's genome using certain biotechnology techniques that have only existed since the 1970s. [3] Human directed genetic manipulation was occurring much earlier, beginning with the domestication of plants and animals through artificial selection .
Genetic testing, genetic engineering, and stem cell research are often discussed together due to the interrelated moral arguments surrounding these topics. The distinction between repairing genes and enhancing genes is a central idea in many moral debates surrounding genetic enhancement because some argue that repairing genes is morally ...
