Abstract

When a gene of one species is transferred to another living organism, it is called recombinant DNA technology. Restriction endonucleases are molecular scissors, used for cutting DNA at specific sites. The human gene is first transferred into a carrier, known as a vector. Most commonly used vectors are plasmids. These vectors are then transfected into host bacteria. These bacteria can then synthesize the desired human proteins. Gene therapy is the intracellular delivery of genes to generate a therapeutic effect by correcting an existing abnormality. Usually, retroviruses are used as vectors to carry normal human gene to the patient\'s cells.
