title: genetics type: Term Paper Genetic engineering is both good and bad for many reasons. The many affects of genetic engineering are seen on some species of plants such acorn; animals such as rabbits; and in humans in in vitro fertilization, artificial insemination, and cloning. Genetics may some day be able to let us clone dieing breeds of animals like the bald eagle. They might even some day bible to clone dinosaurs, as seen in the movie Jurassic Park.
When breeding with plants, scientists take cells that are cut from a plant and placed in a flask with nutrient medium. When the cells grow and divide, they form embryonic, or unformed, tissues, which are transferred to soil where they produce complete plants. These are some of the newest technologies that are around right now. In a few years, genetics will be one of the most important sciences, because of the possibilities of cloning people. There are problems with cloning, though. In the Providence Journal, an article was written on October 26, 1993 called Human cloning: Is it morally right?
and it talks about the many problems of cloning. Dr. Norman Fost said, that, well make 100 Jimmy Carters or 100 Dan Quayles. Headed: Environment plays too large a role.
You could take 100 Hitlerembryos and raise them and never get Hitler. Another problem is that if you wanted to have a family full of Dan Quayles. If you had four children born five years apart, then the fourth would be able to see what the third, second, and first looked like at those different ages. That could possibly cause psychological problems. There are many other different kinds of jobs that have to do with genetics. There are jobs having to do with gene testing where people go tothe doctor find out if there is anything that would make their baby be abnormal.
Tests are now out to see if the parents of the child are carriers, people who do not have the disease but carry one of the two necessary genes for the disease, for some of the many genetic mishaps. The chances of having a child being a carrier is two-in-four. The chances of the child being recipient of the disease is one-in-four, to not be anything is a one-in-four chance. The Punnett square for this problem is Figure A. Sometimes, when this technology of cloning DNA should be used isin the case of some types of turtles that dont breed often. Cloning their DNA would possibly help their species survive.
Another problem with cloning DNA is that of mutation. This may occur as the result of accidental chemical changes in the cell; and long time exposure to: x-rays, ultraviolet rays, and nitrous acid. There have been many patents granted to scientists and farmers for genetically engineered plants. Some of these patents are: corn plants rich inthe amino acid tryptophan, cotton plants resistant to weed-killing herbicides, tobacco plants resistant to various kinds of insects, and potato plants resistant to certain types of viruses. There have also been patents granted inthe field of medicine. Here are some: erythropoietin, a hormone that stimulates blood-cell formation; tissue-plasminogen activator, an anticlottinga agent used to treat heart attacks; and alpha-interferon, which has been found effective in treating hepatitis C.
Genetics is very important in many areas of applied biology and many other sciences, as well.
