genetic engineering
Genetic Engineering is the scientific alteration of genes or genetic material to produce desirable new traits in organisms or toeliminate undesirable ones. Genetic engineering is an umbrella term, which can cover a wide range of ways of changing the genetic material in a living organism. The cells of all living organisms contain genes. By changing an organism's genes, scientists can give the organism and its descendants different traits. Defects of individual genes can cause a malfunction in the metabolism of the body, and are the roots of many "genetic" diseases. To perform genetic manipulation you must first find the gene you want to duplicate or eliminate. Sounds simple? This process has been compared to finding the proverbial 'needle in the haystack'. However, in this case the haystack is about the size of the United Genes are located within cells. Cells are found on tiny structures called chromosomes. Every chromosome contains one molecule of a chemical substance called DNA. One single molecule of DNA can contain thousands of genes. When you put all this together this mass of genes, cells and chromosomes are known as the human genome. A person's DNA contains the information that

How do you feel about the use of Genetic engineering to store to find out which types of foods have been genetically manipulated. Are these foods labeled? The Genetic Revolution has already begun, and it will have as much impact on human society as the Industrial Revolution. It is the course of evolution. Some feel that this type of manipulation is comparable to Nazi Germany's effort to breed "pure Aryans" One could, for example, imagine a herbicide-resistance gene getting into weeds and making superweeds that could take over a However, the huge wave of enthusiasm for genetic engineering is unlikely to subside any time soon. The most current project chromosomes in the human body. As of late 1997, about 50,000 of the human genes had been identified and sequenced, a mere to a young one, have raised the levels of expectations to new heights. produced insulin was the first genetically engineered drug approved by the Food and Drug Administration (FDA) for use on
