Timeline Of Genetically Modified Organisms
Genetic engineering is the science of manipulating genetic material of an organism. The first artificial genetic modification accomplished using biotechnology was transgenesis, the process of transferring genes from one organism to another, first accomplished by Herbert Boyer and Stanley Cohen in 1973. It was the result of a series of advancements in techniques that allowed the direct modification of the genome. Important advances included the discovery of restriction enzymes and DNA ligases, the ability to design plasmids and technologies like polymerase chain reaction and sequencing. Transformation of the DNA into a host organism was accomplished with the invention of biolistics, ''Agrobacterium''-mediated recombination and microinjection. The first genetically modified animal was a mouse created in 1974 by Rudolf Jaenisch. In 1976 the technology was commercialised, with the advent of genetically modified bacteria that produced somatostatin, followed by insulin in 1978 ...

Herbert Boyer
Herbert Wayne "Herb" Boyer (born July 10, 1936) is an American biotechnologist, researcher and entrepreneur in biotechnology. Along with Stanley N. Cohen and Paul Berg he discovered a method to coax bacteria into producing foreign proteins, thereby jump-starting the field of genetic engineering. By 1969, he performed studies on a couple of restriction enzymes of the E.coli bacterium with especially useful properties. He is recipient of the 1990 National Medal of Science, co-recipient of the 1996 Lemelson–MIT Prize, and a co-founder of Genentech. He was professor at the University of California, San Francisco (UCSF) and later served as vice president of Genentech from 1976 until his retirement in 1991. Life and career Herbert Boyer was born in 1936 in Derry, Pennsylvania. He received his bachelor's degree in biology and chemistry from Saint Vincent College in Latrobe, Pennsylvania, in 1958. He married his wife Grace the following year. He received his PhD at the University of P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
