Gene therapy is the transfer of a normal gene into a cell, to correct a defect, or provide other proteins, which are beneficial. Researchers use a carrier vector to deliver a gene into a cell through infection. Doctors administer the vector through intravenously (IV) into the desired body tissue where the cell targeted picks it up. Also, also doctors can take a cell from the body and the vector is delivered in the laboratory by exposing to a vector and then returned to make functioning protein.
Gene is the carrier of information in a cell, which describes how an organ will form or function. When the gene is absent in a cell of an embryo that is supposed to develop a hand, for example, the embryo can create a species without a hand or with a deformation. Doctors will get a gene responsible for hand formation from another cell and deliver it to the cell with a deficiency to make it function normally. The potential benefits of the therapy include eradication of diseases forever, curing genetic disorders, which drugs cannot through defective cell replacement. There is a potential risk of creating unstoppable beings through modification of human abilities as well as creating new disorders once the genes get on the wrong position.
