At least 74 attempts at animal modification where counted in 2015 by A. Lievens et al (2015).

At least 74 attempts at animal modification where counted in 2015 by A. Lievens et al (2015). While genetically modified animals are not yet produced for human consumption on a large scale, news associated with them come up. In 2015 genetically modified salmon was approved in US by the Food and Drug administration and showed up on a market in 2017*. GloFish (Fig. 3.), the first genetically modified pet was around pet shops in US since 2004 (Nash, 2004). | |||
GloFish is interesting because of its aesthetic value. Being a pet, its function is to entertain their hosts. Secondly, GloFish includes green fluorescent protein (GFP), which is widely used in scientific research. GFP modification is also used for educational purposes in high schools and colleges to teach students recombinant DNA or protein purification techniques. Finally, even if genetic modification is restricted for the domestic experiments, the GFP modification was legalized by Berlin authorities in 2016 for educational purposes for the use in home environment. | GloFish is interesting because of its aesthetic value.

Originally isolated from the jellyfish Aequorea victoria, scientists use the protein as markers within DNA sequence or as a concept of proof for genetic modification. Although GFP modification is considered being harmless in organisms, some studies suggest its influence on animal aging, their locomotor ability or eye morphology. Therefore it is suggested to use GFP cautiously for genetical modifications (Mawhinney & Staveley 2011). | Originally isolated from the jellyfish Aequorea victoria, scientists use the protein as markers within DNA sequence or as a concept of proof for genetic modification.

*In 2016 Rüdiger Trojok was using GFP for modifying E. Coli bacteria in his home laboratory. For more info see https://www.meetup.com/Biotinkering-Berlin/events/235107360/?_cookie-check=zc-l_hyy9qe64U94 | |||
