There are teenagers and baby boomers, hipsters and emo kids. A new crop of machismo-challenged heroesâcall them the âemoâ super-dudesâis headed for screens next year. But despite all the chatter about Weezer's influenceâabout nerd rock, or emo, or whateverâI don't really hear it.
Genetic engineering refers to the direct manipulation of DNA to alter an organismâs characteristics (phenotype) in a particular way. Genetic engineering, sometimes called genetic modification, is the process of altering the DNA in an organismâs genome.
An organism that is generated through genetic engineering is considered to be a genetically modified organism (GMO). The first GMOs were bacteria generated in 1973 and GM mice in 1974.Insulin-producing bacteria were commercialized in 1982 and genetically modified food has been sold since 1994.enetic engineering can also be used to remove genetic material from the target organism, creating a gene knockout organism. In Europe genetic modification is synonymous with genetic engineering while within the United States of America it can also refer to conventional breeding methods.
