Gene is made up of DNA. When a new DNA is introduced into the cell of patient to treat a genetic disorders the technique is called gene therapy. Diseases are mostly caused by disease-causing mutated genes, usually new DNA contains a functional gene to correct the effect of mutation caused by mutated gene. The DNA is selected carefully to correct the disease causing gene. Gene therapy is a topic of interest now a days, as many research approaches are testing including;
