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.
When gene transfer occurs, the resulting organism is called transgenic or a GMO (genetically modified organism). Genetic engineering is different from traditional cross breeding, where genes can only be exchanged between closely related species.
