The segments of DNA, which have been associated with specific features or functions of an organism, are called genes. Molecular biologists have discovered many enzymes, which change the structure of DNA in living organisms. Some of these enzymes can cut and join strands of DNA. Using such enzymes, scientists learned to cut specific genes from DNA and to build customized DNA using these genes. They also learned about vectors, strands of DNA like viruses, which can infect a cell and insert themselves into its DNA.
Will they save the earth or destroy it? Will they result in the cornering of the global food market by multinationals or will they bring to mankind the same benefits as genetically engineered medicines? Due to huge advances in science and technology, scientists can now identify and isolate individual genes responsible for producing specific characteristics. By altering such genes, or transferring them to another organism, sci... ... middle of paper ... ...ic resistance gene marker is used, many concerns have been expressed about the possible transfer of antibiotic resistance genes to gut micro organisms which could reduce the efficiency of antibiotics as a treatment. Genetically modified foods differ from normal conventional foods in that it contains or is produced from genetically modified organisms.
Genetic engineering can be carried out in two separate ways. One route is specially designed for bacterial genes and is called the Bacterial Route. The second route is designed for viral and other eukaryotic genes and is called the Gene Gun Route (McInnis and Sinha, 2000). In the Bacterial Route, first scientists isolate the DNA for the desired trait. Then they splice in a gene for antibiotic resistance for tracking ... ... middle of paper ... ...e more responsibility in solving the mysteries of genetic engineering and be more open to scientific breakthroughs in the future.
Genetic Engineering When we envision our future, we usually imagine a future free of disease and physical sickness, but have you ever wondered how a disease-free society will be accomplished? In the twenty-first century our world will be a very different place because of genetic manipulation and engineering. There are many pros and cons to this debate, but it is undeniable that the effects from the new revelations in the field of genetics are far-reaching and deep impacting. Genetic engineering is a radical new technology, one that breaks down fundamental barriers, not only between species, but also between humans, animals, and plants. By combining the genes of dissimilar and unrelated species, permanently altering their genetic codes, novel organisms are created that will pass the genetic changes onto their offspring through heredity.
“Recombinant DNA technology allows DNA to be produced via artificial means. This technology works by taking DNA from two different sources and combining it into a single molecule.” The ideas promoted by Karl Ereky illustrate a direct connection between biotechnology and recombinant DNA. A widely debated application of this technology is in the production of genetically modified foods. This technology has the function of adjusting certain food needs of modern life, facilitating its production, allowing greater number of annual harvests, making it more resistant to pests or enriching the nutritional aspect. On genetically modified food, there is a great controversy, because on one side there are scientists changing a particular food in order to address the socioeconomic needs, while on the other side there are environmentalists who believe that th... ... middle of paper ... ...ility of using recombinant DNA technology to produce products with practical application.” Science heroes such as Ereky, Lobban, Cohen and Boyer provided a basis for the transformation of the biotechnology field, engaging popular audiences and the attention of the government.
Public cities around the world are becoming more involved with a wide array of new technologies without realizing it. From super computers that calculate the movement of satellites without human involvement, to handheld personal computers. Consumers abide with an egregious array of brand new scientific advances that are accompanied by confusing new terms. The food and drug administration, commonly known as the F.D.A, is focusing much of their time with food biotechnology. The all-encompassing use of biotechnology when applied to agriculture and food production increases the deeply felt environmental, economic and ethical concern.
It will soon be possible to engineer and produce human beings by the same technological design principles as we now employ in our industrial processes" (Rifkin 12). In other words, the final goal of genetic engineering is to perfect the human race. Although genetic engineering has many benefits such as gene splicing (combining genes) to cure genetic disorders, it causes concern among many people. ... ... middle of paper ... ...

DNA is what makes you you. It has four nitrogen bases; A, T, C, and G make up the way a person look and develop. This DNA is cut into sequences called By changing the way the protein codes for a specific trait or gene we can make the DNA mutate to a better cell. While changing DNA could lead to cures in the medicine, some say genetic experimentation should not be allowed because it is not safe. Even though the critics do not think that genetic medicine is safe, Americans should all support genetic testing because the testing is revolutionary, more effective, and can cause major diseases to fade away.
Molecular biologists have discovered many enzymes which change the structure of DNA in living organisms, which can intern change the organism. Scientists even started to build vectors which incorporated genes of their choosing and used the new vectors to insert these genes into the DNA of living organisms. The International Chiropractic Pediatric Association believes that there are many downfalls and moral impediments in the allowance of genetic cloning of humans including a diminished the sense of uniqueness of an individual, the fact that it is inherently unsafe, and it may cause faults in parent-child interaction. Reproductive cloning would weaken the sense of uniqueness of an individual. It would intrude upon deeply and widely held beliefs about human individuality and freedom, and could cause a devaluing of clones in contrast with non-clones.
The proper definition of genetic engineering is, "Genetic Engineering, the alteration if an organism's genetic, or heredity, material to eliminate undesirable characteristics or to produce desirable new ones"(Encarta 1). The initial purpose of genetic engineering was to increase plant and animal production, diagnose diseases and improve or invent new medical technologies such as vaccines and other useful drugs. The methods are now being abused. Ronnie Cummins explains it as, a radical new technology, one that breaks down fundamental genetic barriersnot only between species, but also between humans, animals, and plants. By combining the genes of dissimilar and unrelated species, permanently altering their genetic codes, novel organisms are created that will pass onto their offspring through heredity.
