The correct answer should be something like: "Gene therapy involves the use of bacteria or viruses to deliver new or modified genes to cells". That is what can be concluded based on the paragraph you provided.
Answer:
Gene therapy is the introduction of normal genes into cells in place of missing or defective ones in order to correct genetic disorders. which often involves the use of bacteria or viruses to deliver new or modified genes to cells.
Researchers are testing several approaches to gene therapy, including:
- Replacing a mutated gene that causes disease with a healthy copy of the gene.
- Inactivating, or “knocking out,” a mutated gene that is functioning improperly.
- Introducing a new gene into the body to help fight a disease.
