Ernesto Sanchez BIO: 187 Instructor: Anna April 16, 2012 Duchenne Muscular Dystrophy Even though funding organisms were knowing to function as a perfect machine, distinguishable heritable errors occur occasionally. Many of these cistrontical disorders ar caused by abnormalities in genes or chromosomes. In other worlds, persons deoxyribonucleic acid strands be affected. There are many divers(prenominal) types of genetic disorders; some are inherited from the parents, while others are caused by acquired changes, or mutations in a previous stem of genes. Since generic wine disorders are present before birth, and the injure from these diseases are irreversible. wizard of the most common genetic diseases to take care is Duchenne muscular muscular muscular dystrophy. find in 1961 by Guillaume B.A Duchenne, muscular dystrophy is a scourge disease to inherit. To begin with, Duchenne muscular dystrophy is a archaic inherited muscularity disease characterized b y forward-looking muscle weakness and wasting. People who suffer from muscular dystrophy are missing the protein called dystrophin, without this protein muscles cannot develop normally and muscles cells are lento to pick up (Kliegman , Bethrman , Jenson, Stanton 153). As seen in manikin 1, when a person is born(p) with this disease their muscles do not produce dystrophin.

The drop of protein abate the muscle function and the muscle eventually losings strength. In the late stages of muscular dystrophy, muscle fibers often are replaced by fat and connective tissue. This can be seen in figure 2, the patients muscles are abnormal develop. Duchenne muscular dystrophy is caused by fa ulty or missing genetic information that pre! vents the consistence from qualification the proteins needed to build and maintain healthy muscles. The gene gather up in the process is called dystrophin (DMD) gene. The dystrophin gene is the largest gene found in nature and is the one that produces a protein called dystrophin. This protein is placed primarily in muscles used for movement (skeletal muscles) and in heart...If you penury to get a full essay, order it on our website: OrderEssay.net
