Genetics and Progeria
The Disease of Premature Aging
Genetics and Progeria; The Disease of Premature Aging
Genetics has made some fantastic advances recently in science. For all that we
have learned, we still haven’t found the answers to everything. The last three or four decades have witnessed an unquestionable revolution occurring in the study of genetics. Since the 1940's when DNA first was clearly postulated, up to the discovery of the nature of the genetic code in the 1960's when DNA was proved to be a storehouse of genetic information, researchers in genetic engineering have become almost commonplace. Then why haven’t we found the answers to life, you might ask? Well for as much as we know we are still making discoveries everyday. As is evidenced in the study of Progeria a genetic disease that causes premature aging, it will be apparent how much further we have to go.
In today’s world we take it for granted that every one knows what genetics are and how we study it. The study of genes and DNA help us traverse the world of medical mystery. In the study of genes and the function is the study of disorders or rather anomalies within the gene make-ups of various individuals that caused malfunctions, or disorders. Genetic disorders are medical conditions caused by mutations in a gene or a set of genes. Mutations are changes in the DNA sequence of a gene. DNA is the chemical in side the nucleus of a cell that carries the generic instructions for making living organisms. They can happen at any time in our lives including when we are first forma dn a single cell right up until our deaths. Now not all mutations cause disorders because the mutations are repaired. “Our cells have mechanisms for repairing DNA if mistakes are made in the sequence or if the DNA is damaged.” (2003, Audesirk, Byers)
Mutations of the genes can happen in different ways but primarily they happen naturally or by environmental...
