Recombinant DNA is widely used in biotechnology, medicine and research. Today, recombinant proteins and other products that result from the use of rDNA technology are found in essentially every western pharmacy, doctor's or veterinarian's office, medical testing laboratory, and biological research laboratory.
Gene therapy is when DNA is introduced into a patient to treat a genetic disease. The new DNA usually contains a functioning gene to correct the effects of a disease-causing mutation. 1  Gene therapy uses sections of DNA (usually genes) to treat or prevent disease. Gene therapy uses sections of DNA (usually genes) to treat or prevent disease. 2  The DNA is carefully selected to correct the effect of a mutated gene that is causing disease. 3  The technique was first developed in 1972 but has, so far, had limited success in treating human diseases.
