Gene Therapy is a technique used to correct defective genes responsible for disease development. There are four different ways to correct genes.
*A normal gene can be inserted in place of the defective gene. This is the most common approach in gene therapy.
*An abnormal gene could be swapped or a normal gene in a homologous recombination.
*The abnormal gene could be repaired through selective reverse mutation, which would change the gene back to a healthy one.
*The regulation (degree to which a gene is turned on or off) of a particular gene could be altered.
To do any of these altercations, a carrier molecule, also called a vector, must be used to deliver the therapeutic gene to the patients target cells. These vectors are sent to a location chosen by the doctor or scientist. If any slight problem occurs, the person could be worse off than before. This process is too new for human trial and error in our groups perception. We have decided that, if properly tested, this process could be life changing for the people it helps, but it still has a long way to go before being safe. It is a good idea though, and we think research should definitely continue.
