Question

Quizplus · Accepted Answer

Gene therapy can be used to replace or repair nonfunctional genes that are responsible for producing enzymes or proteins that the body needs. Diseases caused by nonfunctional enzymes or proteins, such as cystic fibrosis, hemophilia, and sickle cell disease, could be successfully treated by gene therapy. Gene therapy is not effective against diseases caused by external factors such as excessive fat intake or bacterial infection. While gene therapy is being researched as a potential treatment for cancer, its effectiveness in treating cancer has not yet been fully established.
