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 is any process by which genetic material (the building blocks of heredity) is changed in such a way as to make possible the production of new substances or new functions.As an example, biologists have now learned how to transplant the gene that produces light in a firefly into tobacco plants.he term vector means any organism that will carry the gene from one place to another. The most common vector used in genetic engineering is a circular form of DNA known as a plasmid. Endonucleases are used to cut the plasmid molecule open at almost any point chosen by the scientist.
