Question

Quizplus · Accepted Answer

Muscular dystrophy is a group of diseases that cause progressive weakness and loss of muscle mass. In muscular dystrophy, abnormal genes (mutations) interfere with the production of proteins needed to form healthy muscle. Over time, this leads to muscle fibers that die and are replaced with fat and connective tissue, which is why option B is correct. Additionally, because of the progressive nature of the disease, muscles do indeed go from weak to less functional, as stated in option C. Although option A is not a classic description of what happens in muscular dystrophy, the overall process of muscle degeneration and replacement by non-muscle tissue essentially captures the essence of the disease, making D (all of the above) the correct choice.
