Turning Back Time Essay -- Biology Essays Research Papers

Turning Back TimeProgeria, an extremely rare affection caused by a slight ancestral defect, victimizes every 1 in 4 million children. , (3). At the moment, there are twelve cases of Progeria in the US, and no more than one hundred have been reported around the world. magic spell the child suffering from Progeria go out appear to have no symptoms at birth, the tell tale signs of the fatal disease will begin to pop out within a few months, (1). The common first symptom of a child who may be a Progerian is that the ends of their shoulder bones will be re-absorbed into their bodies. Soon, he or she will be underweight and small for his or her age. Hair loss and dental decay will follow. The disease slowly eliminates body fat. Eventually the Progerian will become afflicted by arthritis and take on the appearance of a person five to ex times their age, (6).On average, a Progerian will live to be thirteen. Usually their demolition will be due to a cardiovascular disease such(prenomi nal) as heart attack or stroke.Over the past quartet years, a lot of progress has been made studying Progeria. investigateers have conclude the cause of this disease is most likely due to a case-by-case letter misspelling in the genetic code on a single chromosome, which is a coiled strand of DNA within the jail cell. After examining twenty Progerians, eighteen were strand to have the same genetic abnormality. The 19th case had a similar misspelling in a nigh gene. The 20th case did not have classic Progeria, (2).The gene which was found to be abnormal in eighteen of the cases, is responsible for making the protein called lamin A. If this protein is defective, untimely cell death occurs. This protein structures the inner layer of membrane surrounding the nucleus. to each one Progerian e... ...theory of evolution could be found on the cover of a stylemark birthday card.
