Are Genetically Modified Organisms a good thing? In order for geneticists to comprise one organism expressing certain beneficial characteristics from another, cross breeding of some kind has to take place. For centuries people have been cross breeding all kinds of organisms (mostly crops and animals) in order to develop these beneficial traits. However, nature has natural barriers protecting against non-sexually compatible species breeding and so for this sharing of characteristics to take place they have to insert DNA (often in modified form from that of the original species) directly into the chosen organism. The modified DNA then codes for a protein within the organism (different from its natural one) giving rise to a new (and hopefully beneficial) characteristic, which will then be expressed. Engineered organisms of this kind are said to be "genetically modified" or GM, but however they are referred to, the simple similarity between them all is that their...
