Question

what treatment(s) cure sickle-cell anemia?
○ narcotics and blood transfusions
○ gene therapy
○ episode-reducing medication
○ bone marrow transplants
○ bone marrow transplants and gene therapy

Explanation:

Bone marrow transplants replace defective blood - forming cells. Gene therapy aims to correct the genetic mutation causing sickle - cell anemia. Narcotics and blood transfusions manage symptoms but don't cure. Episode - reducing medication helps with crises but isn't a cure. So the combination of bone marrow transplants and gene therapy has the potential to cure sickle - cell anemia.
