1564 Words Jun 9th, 2015 null Page
Genetic engineering is a process by which genomes are modified. This process is done by cloning. The genetically modified organism that carries a gene from a different species, called transgenic. Genetic engineering can also be referred to as cross-breeding or gene-swapping. In 1953, Francis Crick and James Watson discovered the structure for the chemical molecule, Deoxyribonucleic acid. DNA is a substance that carries genetic information in the cells of plants and animals, and occurs in the nuclei of all living cells. A genetically modified organism (GMO), is an organism whose genome has been modified by genetic engineering. GMO’s can range from alteration of crops, human genomes, as well as animals. Gene therapy gives researchers a reason to support genetic engineering. Gene therapy is a technique that treats and prevents diseases. This type of therapy can be treatment for illnesses such as: heart attacks, sickle-cell anemia, cystic fibrosis, and Alzheimer’s disease. Genetic engineering can also determine the genotypes of humans. This helps with the early detection of diseases to possibly prevent them from progressing. The process of genetic engineering is not supported because of how expensive it is, the professional equipment needed, and the possibility of the gene transferring process to go wrong. There is also a possibility that the gene being inserted may not land in the spot intended. Genetically modified crops can be at a disadvantage because the gene being inserted…
