What is the main goal of gene therapy?

The main goal of gene therapy is to treat or prevent disease by correcting faulty genes. This therapeutic approach targets genetic disorders caused by mutations or abnormalities in specific genes. By introducing, removing, or altering genetic material within a patient's cells, gene therapy aims to restore normal function, thereby addressing the underlying cause of the disease rather than just managing the symptoms.

Gene therapy can potentially provide long-lasting effects, as it aims to rectify the genetic issues that lead to conditions like certain inherited disorders, some types of cancer, and viral infections, among others. This method represents a significant advancement in the field of medicine, offering hope for previously untreatable conditions.

The other choices focus on unrelated goals, such as eliminating bacteria, enhancing appearance, or improving cognitive functions, which do not align with the therapeutic intention behind gene therapy.
