May 22 – The first gene transfer experiment in humans takes place, leading to full-fledged gene therapy trials by September 1990. The gene responsible for the cystic fibrosis transmembrane conductance regulator was discovered. Mutations of the gene are considered causes of cystic fibrosis.
John Gurdon clones an animal, a frog tadpole, from an egg cell using the nucleus from an intestinal cell (1962). Roger W. Sperry shows the potential independence of the two sides of the human brain using split-brain patients (1962–1965). Nirenberg and Leder experiment, binding tRNA to ribosomes with synthetic RNA to decipher the genetic code ...
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]
Hershey–Chase experiment proves that phage genetic material is DNA. 1952: The Hershey–Chase experiment proves the genetic information of phages (and, by implication, all other organisms) to be DNA. [29] 1952: an X-ray diffraction image of DNA was taken by Raymond Gosling in May 1952, a student supervised by Rosalind Franklin. [30]
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.
1980 – The U.S. patent for gene cloning is awarded to Cohen and Boyer. 1982 – Humulin, Genentech's human insulin drug produced by genetically engineered bacteria for the treatment of diabetes, is the first biotech drug to be approved by the Food and Drug Administration. 1983 – The Polymerase Chain Reaction (PCR) technique is conceived.
One such experiment was the cloning of recombinant DNAs derived from highly pathogenic organisms. In addition, neither the cloning of DNA containing toxin genes, nor large scale experiments using recombinant DNAs that were able to make products that were potentially harmful to humans, animals or plants were allowed under the guidelines.
