Genetically Modified Foods - Essay Example
Pages 5 (1255 words)
Genetically engineered foods are produced by altering the genetic make-up of crops using recombinant DNA technology, or gene splicing, to incorporate a desirable trait in a plant. Genetically engineered foods are also known as biotech, bioengineered, and genetically modified foods, although "genetically modified" may also refer to foods from plants altered through other breeding methods, says James Maryanski, Ph.D., the FDA's food biotechnology coordinator…
And the many varieties of apples we eat today were produced through genetic modification.
Traditional genetic modification methods, such as cross-fertilization can produce a desired trait, such as a sturdier plant. Using these methods, scientists mix thousands of genes from several plants to weed out the unwanted traits by multiple attempts at cross-breeding and selective breeding.
Modern methods of genetic modification like genetic engineering are more precise, predictable and instant. By controlling the insertion of one or two genes into a plant, scientists can give it a specific new characteristic without transferring undesirable traits.
GE is a revolutionary new and fast growing technology. This technology involves randomly inserting together the genes of non-related species, utilizing viruses, antibiotic-resistant genes, and bacteria as vectors, markers, and promoters and permanently altering their genetic codes and creating gene-altered organisms that pass these genetic changes onto their offspring through heredity.
In some cases chemical additives manufactured by genetically engineered bacteria may also be classified as genetically engineered foods. ...
