Introduction Genetic engineering is the process of modifying the genetic makeup of an organism, whether it is an animal, a plant, or a bacterium, with the use of technology. This can be accomplished through the use of recombinant DNA (rDNA), which is DNA obtained from two or more distinct organisms and then combined into a single molecule, according to the National Human Genome Research Institute (NHGRI). In the early 1970s, recombinant DNA technology was developed, and the f

Introduction Gene therapy is the process of delivering therapeutic DNA into the cells of a patient in order to treat disease with DNA as a drug. It is most frequently used to replace a faulty gene with DNA encoding a functional, therapeutic gene. Alternatively, a mutation can be corrected directly or a patient can be treated with DNA encoding a therapeutic protein medicine (rather than a genuine human gene). Gene therapy involves packaging DNA encoding a therapeutic protein i
