Genetics Cutting Edge Projects
This is an excerpt from the paper...
Genetics today is on the cutting edge of biological science, and scientists working in this area are involved in a wide variety of pursuits that will have profound implications for our future on this planet, with projects including the creation of new biologic entities, curing diseases, manufacturing synthetic versions of biologic substances, identifying different genetic codes and what they do, and perhaps finding a way to control that genetic information to produce animals with certain characteristics or without certain characteristics, including greater strength, resistance to disease, and a higher yield in meat, eggs, dairy products, or whatever they provide. Geneticists have already accomplished many of these things with grains, plants, and even certain farm animals. They are addressing disease through the creation of new strains of bacteria by means of recombinant DNA technology. Speculation about the future may be surpassed by the reality in a very few years. Recombinant DNA is DNA molecules derived from different sources that have been artificially spliced together in vitro to form novel hybrid DNA molecules not normally encountered in nature. Modern genetic engineering techniques based on recombinant DNA permit genetic exchanges between species that do not normally interbreed thus offering the opportunity for us to transcend the limits imposed by nature on hereditary processes. Using these techniques, scientists can manipulate genes individually by directly mod

Genetic experiments also hold out hope for the cure of diseases with substances that do not yet exist or that have not been harnessed to this particular purpose. Experiments with gene therapy represent a giant step into the medical possibilities of the future. An advisory committee at the National Institutes of Health keeps a tight rein on such experiments and recently approved three gene therapy proposals to treat cancer and a deadly inherited form of high cholesterol. Other scientists have rigged the lining of blood vessels with genes that deliver anticlotting drugs, and still others are exploring genes that could make cells resistant to the AIDS virus (Brownlee & Silberner, 1991, p. 64).
Geneticists have engineered new strains of plant to produce more crops or to change the nature of the crops produced. Agricultural researchers are constantly trying to design better produce with selective breeding, the use of mutagens, and genetic engineering. Among the breakthroughs made in recent years have been the production of miniature head lettuce, spherical zucchini, broccoflower, and other such delicacies (Kluger, 1993, pp. 36-40). Other scientists have been working on genetic protections for differ
