Human Gene Therapy Human gene therapy is a method used in the medical field that treats diseases at the molecular level, solving the source of the problem; our genes. Today, diseases and disorders are commonly treated by addressing the symptoms, the surface of the problem. Many disorders and diseases are caused by faulty proteins, and within those faulty proteins are damaged, faulty genes. These faulty genes can be treated through gene therapy. Gene therapy is not new and has been developed and improved by researchers over the past two years. Being an experimental technique, gene therapy also has its pros and cons, but so far it is showing positive and increasing success rates. Gene therapy works by introducing new, functioning genetic material into damaged genes to help them function and produce beneficial proteins. If a gene is inserted directly into a cell, it usually won't work. Then, to complete this task, a vector, a modified virus, is used to carry and deliver the new gene. There are two different categories of vectors that can be used in this process; recombine...
