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.
If genetic material from the same species or a species that can naturally breed with the host is used the resulting organism is called cisgenic. Genetic 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.enetic engineering alters the genetic make-up of an organism using techniques that remove heritable material or that introduce DNA prepared outside the organism either directly into the host or into a cell that is then fused or hybridized with the host.
