Gene Therapy: An Introduction to DNA

Gene therapy potentially represents one of the most important developments to occur in the field of medicine. Gene therapy is an experimental technique that uses genes to treat or prevent diseases. This technique may allow doctors to treat a disorder by inserting a gene into a patient’s cells instead of using drugs or surgery. As gene therapy has moved from the laboratory into the clinic, several issues have emerged as central to the development of this technology: gene identification, gene expression and gene delivery.
