One of the ways scientists suggest to find a treatment for muscular dystrophy is

The correct option is: attempt to correct defective genes so it creates the right proteins.

To understand why this is the correct approach proposed by scientists, we can break down the science behind muscular dystrophy:
1. Genetic Basis of the Disease: Muscular dystrophy is a group of inherited genetic disorders. It is caused by mutations (errors) in the specific genes that provide instructions for producing proteins essential for building, maintaining, and repairing healthy muscles.
2. The Missing Protein Link: When these genes are mutated or defective, the body cannot produce the correct proteins, or produces them in a non-functional state. For example, in Duchenne muscular dystrophy, a mutation in the dystrophin gene prevents the production of dystrophin, a crucial protein that helps keep muscle cells intact. Without it, muscle fibers damage easily and degenerate over time.
3. Targeting the Root Cause: While physical therapy and customized diets can support overall health, they do not repair the damaged muscle tissue or address the underlying cause of the disease. By using gene therapy—such as introducing a functional copy of the gene, editing the genetic mutation, or using molecular tools to bypass the error—scientists aim to enable the cells to successfully manufacture the correct, fully functional proteins. This gene-correction approach directly targets the source of the degeneration to potentially halt or reverse the disease.
