The reason the muscles are mutated and do not function as well in Duchenne muscular dystrophy (DMD) is due to genetic mutation. This is the main reason that an individual becomes diagnosed with this disease. During the process of genetic coding, the X chromosome becomes mutated; surrounding the muscle-fiber membrane, is the protein dystrophin, which is associated with the X chromosome. Dystrophin provides protection for the muscles and the strength for muscles to not deteriorate. In this case, dystrophin becomes poor or nonexistent in the body because the mutated gene is not able to functionally produce it. The bundles of muscle fibers begin to weaken and not work properly until there is a total absence of dystrophin in the muscle cells, which
