In Duchenne muscular dystrophy,which protein is directly affected?

B) actin
C) dystrophin
D) myoglobin
E) hemoglobin

Question

Quizplus · Accepted Answer

Duchenne muscular dystrophy is caused by mutations in the gene that encodes dystrophin, which is a structural protein that helps to stabilize and protect muscle fibers during contraction and relaxation. Without functioning dystrophin, muscle fibers become weakened and eventually die, leading to progressive muscle weakness and loss of function. Myosin and actin are contractile proteins involved in muscle movement, but they are not directly affected by dystrophin deficiency. Myoglobin and hemoglobin are oxygen-binding proteins found in muscle and blood, respectively, and are not related to Duchenne muscular dystrophy.
