What is the primary role of the gene product Dystrophin?

• A. Blood clotting
• B. Muscle stability
• C. Hormonal regulation
• D. Cellular communication

Answer: (B)

The gene product Dystrophin plays a crucial role in muscle stability. It is a protein that is essential for the structural integrity of muscle fibers. Dystrophin acts as a connector between the inner cytoskeleton of muscle cells and the extracellular matrix, which helps to stabilize the muscle cell membrane during contraction and relaxation.

Without proper functioning of Dystrophin, the muscle fibers can become damaged over time, leading to conditions such as Duchenne Muscular Dystrophy, which is characterized by progressive muscle weakness and degeneration. This highlights the importance of Dystrophin in maintaining the strength and stability of skeletal muscles.

Other functions mentioned in the options, such as blood clotting, hormonal regulation, or cellular communication, do not pertain to Dystrophin's role. Each of these processes involves different proteins or mechanisms within the body that address those specific biological needs.
