FAQs on Biotechnological Applications in Medicine: Molecular Diagnosis
Q1. What is gene therapy?
Answer: Gene therapy is a type of medical treatment that uses genes to treat or prevent diseases. Gene therapy may involve replacing defective genes with healthy ones, adding new genes to help the body fight diseases, or destroying harmful genes.
Q2. How does gene therapy work?
Answer: Gene therapy works by delivering new genes to cells in the body. The new genes can either replace defective genes or help the body fight diseases. Gene therapy can be done using a variety of methods, including injections, oral doses, and gene-carrying viruses.
Q3. What are the potential applications of gene therapy?
Answer: Gene therapy has the potential to treat a variety of diseases, including cancer, heart disease, diabetes, and neurological disorders. Gene therapy may also be used to improve the success of organ transplants and to prevent the spread of HIV and other infectious diseases.
