Genetic modification, the food that everyone fears a lot but understands very little. But the fact is that you probably ate a genetically modified organism for lunch.
Genetically modified foods or GM foods, are foods produced from organisms that have had changes introduced into their DNA using genetic engineering. Genetic engineering allow for the introduction of new traits as well as greater control over traits than previous methods such as selective breeding and mutation breeding. Genetically engineered organisms are generated and tested in the laboratory for desired qualities. The most common modification is to add one or more genes to an organism 's genome. genes can also be removed or their expression is increased or silenced or the number of copies of a gene is increased or decreased. Once satisfactory strains are produced, the producer applies for regulatory approval to field-test them, called a "field release." Field-testing involves cultivating the plants on farm fields or growing animals in a controlled environment. If these field tests are successful, the producer applies for regulatory approval to grow and market the crop. Once approved, specimens (seeds, cuttings, breeding pairs, etc.) are cultivated and sold to farmers. The farmers cultivate and market the new strain. In some cases, the approval covers marketing but not cultivation. Goals of genetic engineering include
1: use genetic engineering to protect organism from environmental threats, such as cold,…
