Essay The Benefits Genetic Engineering for Medical Purposes

Genetic engineering has developed very rapidly in the past two decades. This is also one of the most controversial topics in the United States. From research on gene therapy to cloning of various animals, genetic engineering can save lives and put them at risk. Politics, science and many other organizations are intensely discussing many pros and cons. For the most part we focus on the idea of ​​using stem cells as a treatment for disease.

Stem cells are cells that can grow into various types of cells in the body. As a body restoration system, they can theoretically take over other cells without limitation ... Read more

Scientists thought that human adult stem cells could be used once, but that the cells may be damaged by sunlight and airborne toxins, and that adult stem cells may contain more DNA When the scientists discovered this idea was solved quickly. It is abnormal. Stem cell research can cure cancer, Alzheimer's disease, Parkinson's disease in one day (National Institutes of Health, FAQ, 1)

Do you know that diabetic patients can transform animal corpses into insulin by DNA manipulation science? Early in the 1980s, scientists isolated human genes of insulin and transferred them to bacteria. Bacterial cultures are currently used to produce large amounts of human insulin. DNA manipulation is particularly important in genetic diseases such as Huntington's disease, as well as in medicine that can cure even some cancers. Live cells use several major types of DNA engineered enzymes. The first type is DNA polymerase, which cells use to replicate their own DNA. The next type is DNA ligase, which combines two DNAs to form a single fragment. The third type is a restriction enzyme, it seems to be made only with bacteria. Restriction enzymes are very important enzymes essential for our DNA manipulation (Rapoza, DNA, 2)

Another way to manipulate DNA is by cloning. Cloning is the creation of a complete copy of the original, like a copy machine. In the case of DNA molecules, cloning means introducing new DNA into it.

Genetically modified organisms (GMOs) are organisms of various types, shapes, and sizes that are genetically engineered using genetic engineering to achieve a specific purpose. Today, bacteria, viruses, plants and animals bring various benefits through genetic engineering, and for them as well as us. Therefore, GMO is used in various fields such as industrial, pharmaceutical and food production. However, not everyone agrees to use genetic engineering for such a purpose because of the potential risk to health and the environment, or due to ethical issues.

Genetic engineering is currently growing fastest and is probably the most controversial science field. Genetic engineering decodes and manipulates DNA for scientific and medical purposes. "The discovery that human cells can grow in culture dishes opens up the surprising possibility of curing the disease and the confusion of moral complications" (Allen 9). Genetic engineering has become most useful in the medical field. - During the Adolf Hitler regime, many American companies and scientists have contributed to the progress of eugenics research and they should be responsible for atrocities committed during World War II . It began in the late nineteenth century by Francis Galton who believed that "must improve today's lowest level human breeding and nurture the best in the best way" will occur. Despite the massive participation of the United States, many European scientists and governments are supporting this research.
