GENE THERAPHY

Each gene has a special job to do. It carries blueprints(said to be instructions).
Each of our biological parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes we have. Genes that are passed on to us determine many of our traits, such as our hair color and skin color and many other characteristics. Nowadays scientists are very busy studying genes.
Gene therapy uses the technology of genetic engineering to cure or treat a disease caused by a gene that has changed in some way. This is a new kind of medicine, and scientists are still doing experiments to see if it works. One method they are trying is replacing sick genes with healthy ones.Gene therapy is the insertion of genes into an individual's cells and tissues to treat diseases, such as hereditary diseases.Although the technology is still in its infancy, it has been used with some success. Scientific breakthroughs continue to move gene therapy toward mainstream medicine.The biology of human gene therapy remains complex and many techniques need further development.Gene therapy is nowadays the basis to many entertainment programs and popular video games.
