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 ...
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, 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 .
The first genetically modified animal to be commercialised was the GloFish, a Zebra fish with a fluorescent gene added that allows it to glow in the dark under ultraviolet light. [31] It was released to the US market in 2003. [32] The first genetically modified animal to be approved for food use was AquAdvantage salmon in 2015. [33]
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. There are a number of steps that are followed before a genetically modified organism (GMO) is created.
Genetic modification involves the directed insertion, deletion, artificial synthesis or change of nucleotide bases in viral genomes. Genetically modified viruses are mostly generated by the insertion of foreign genes intro viral genomes for the purposes of biomedical, agricultural, bio-control, or technological objectives. The terms genetically ...

Genetic modification usually describes the insertion of a transgene (foreign DNA, i.e. a gene from another species) into a random location within the genome. [ 13 ] [ 14 ] Gene-targeting is a specific biotechnological tool that can lead to small changes to the genome at a specific site [ 2 ] - in which case the edits caused by gene-targeting ...
