A Brief Discussion of Genetic Diseases Essay -- Biology Genetic Disease

Since the discovery in 1928 via the Griffith experiment (an experiment dealing with bacterial transformation) that DNA carried genetic information, many important discoveries have been made regarding the human genome and its point in the determination of phenotypic traits. Not least of these is the discovery and study of genetic disorders, or diseases caused by abnormalities within the genes. Disorders of this nature can be caused by a variety of factors. Some diseases such as Huntingtons disease must be inherited, while others, such as some cancers, can be the gist of environmental factors slowly mutating the genome over time. Still others can result from random errors in normal DNA replication. Typically, genetic disorders tend to be rare ascribable to the ability of DNA to repair itself and also because of the tendency for damaged cells to undergo programmed cell death to preserve the overall health of the organism. However, when genetic disorders do appear, the y illustrate a considerable problem for the afflicted, because although some are treatable and possibly manageable, very few, if any, are ever curable. DNA of a living individual cannot be alter by any existing technology. Nevertheless, research is continually improving our ability to treat these diseases, particularly with diseases such as cancer, trisomy, and Huntingtons disease. Of particular interest in unexampled medicine is the study of the various forms of cancer and the genes involved in causing it. Cancer is a disease in which cells of the body mutate to the point where they brook the ability to regulate their division and DNA replication, causing uncontrollable growth to the extent of interfering with the function of normal, healthy cells... ...gtons Research. 26 August 2007. 1 celestial latitude 2010 .National Cancer Institute.
