DNA Technology in Medicine

Extracts from this document...


DNA Technology in Medicine 4th of April 2002 The intervention of humans in nature has increased dramatically as the years have gone by. As we start this millennium, a very powerful new technology with much potential is being unravelled that will allow humans to continue unearthing nature's secrets, and to continue tinkering with them: DNA technology. With the human genome fully sequenced, the possibilities to apply DNA technology in a field such as medicine are tremendous. Imagine: drugs tailored to your DNA, that work the first time round leaving no side effects; predictive medicine that will tell you what diseases you might some day suffer, and the gene therapy that is best suited to curing them; the elimination of a genetic disease you have even before your birth; medical checks that involve but a blood test. The possibilities are indeed great. The risks are also great as this technology goes through its baby-steps. Will its benefits be accessible to everyone? Is it dangerous to play with nature? Will its use be adequate to our real needs? Just how far should we go with it? ...read more.


Therapeutic proteins already exist, but with genomic knowledge, the market which was valued at around 20 billion dollars in the year 2000, will boom.7 Research commissioned by The Guardian shows that pharmaceutical companies, biotech firms of all sizes, government institutes and universities have filed patents on a staggering 127,000 human genes or partial human gene sequences.8 Many companies and universities are striving to patent as many genes as they can, without even knowing their function, so that in the future they might prove to be a gold mine. It costs around 250,000 dollars to keep a patent alive, so the magnitude of these investments is quite large.9 All these investigations that represent investments by the billions will with time find cures to many of the diseases that flog human life, but will they only have positive effects? If medicine based on genomic knowledge proves to be as powerful as it seems, then the roles of doctors might be minimized; why need a doctor when a DNA computer chip will tell you what you have, and then prescribe a tailored drug that will work only for you? ...read more.


The potential benefit we can receive from it is very great, but if this benefit isn't maximised around the whole world, and we end up misusing it, I believe it will not be as valuable to the world as it could be. 1 Tagliaferro, Linda and Bloom, Mark V.

    This is an unsound method to obtain, since it ignores and omits any necessity to assess the ethical and moral problems involved in either of these alterations techniques, whatever one's view of them. It also appears to mean that to have ethical reservations at this stage is being observed by the medical profession as heterodox.

    In addition, only characteristics that are determined by one or a few genes can be transferred. The technology of genetic engineering does not enable scientists to transfer behavioral traits, such as intelligence, that are a complex mixture of many genes and the effects of cultural conditioning.

    but the genome of some tumor viruses appears to survive within the cell as a separate unit and to reproduce independently. At the moment it seems that the persistence of the viral genome is necessary for viral oncogenesis, either to maintain the influence of an oncogene over the cell or

    There is always risk of allergies when using drugs and for some unfortunate people drugs may do more damage than good. 3) Side affects of drugs vary from person to person and it is impossible to know beforehand how a certain drug will affect an individual.

  2. Outline and Critique the Claim that GeneticTherapy is justified but Genetic Enhancement is not

    The implication of this enhancement aim of treatment is that the genes which are inserted might be pretended to boost the functioning of normal genes. In other case, the normal genes could be replaced with other engineered genes due to produce a desired higher ability than the normal ones. 3.

  1. Explain how DNA fingerprinting works.

    The accuracy of the test depends on the closeness of the markers to the faulty genes. In certain cases, the test cannot give useful information to the healthy members, as there are no reliable markers available. Many of the cancer susceptibility genes that are known about today, were discovered through
