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.
Genetic engineering can be used to create organisms that produce large amounts of useful substances-for example, bacteria can be engineered to produce human insulin to treat diabetics.Genetic engineering can also be used to create and store DNA fingerprints, which can be used for identification purposes.enetic engineering involves altering the genetic code [genetic code: The universal code that DNA or mRNA in every living organism uses to carry information about the sequences of amino acids in its proteins.] of an organism by inserting a gene [gene: The basic unit of genetic material inherited from our parents.
