Question

patient 2
1.1.which biomolecule is most associated with the muscle loss lexi is having as a result of her muscular dystrophy?
2.justify your answer to number 1 using evidence

Explanation:

1. In Muscular Dystrophy, the protein dystrophin is often affected. Dystrophin is a crucial biomolecule in muscle - it helps maintain the integrity of muscle cell membranes. Mutations in the gene that codes for dystrophin lead to its deficiency or malfunction, which is a hallmark of many forms of Muscular Dystrophy and results in muscle loss over time.
2. Research shows that in Duchenne Muscular Dystrophy, the most common and severe form, there is a complete absence of dystrophin due to mutations in the DMD gene. Muscle biopsies of patients with Muscular Dystrophy often show reduced or absent dystrophin levels compared to healthy individuals, which is strong evidence linking dystrophin to the muscle - wasting symptoms of the disease.

Answer:

1. Dystrophin
2. In Duchenne Muscular Dystrophy, there is a complete absence of dystrophin due to gene mutations. Muscle biopsies of Muscular Dystrophy patients show reduced or absent dystrophin levels compared to healthy individuals.
