There is a breakthrough in chemical surgery that can correct some types of genetic mutation. Proteins do not start with this shape. In recent years, DNA has been used frequently for criminal cases. To further back this theory up I think that this is why without immune suppressors people that have been given an organ transplant just reject their new organs because the organs don’t have the same barcode. The DNA is unzipped and copied. This especially helpful in legal cases and will give finality on a particular child’s identity. You can determine migration patterns and discover your ancestral origins. But aside from these applications, analysis of DNA is also used in the fields of anthropology, paleontology, and archeology.

If we trace the roots of today's cutting-edge technologies like DNA fingerprinting, genetic engineering, and genome sequencing back in time, we will find ourselves once again in the X-ray diffraction lab at the University of London and tinkering with models at Cambridge. In most living organisms, DNA is stored mostly on the nucleus of the cell. By gently stirring the alcohol layer with a sterile pipette, a precipitate becomes visible and can be spooled out. Our white blood cells (among other things obviously) scan cells/items that come into contact with them and if they have the right barcode they do nothing and move on if however they find another barcode (in the case of fluid transfer or organ transplants) or non at all (debris from a cut entering our bodies) it sends out an alert to deal with the foreign object. We do not know what most of our DNA does, nor how, or to what extent it governs traits. DNA is revolutionizing the field of forensic science and contributing effectively to safeguarding our society.
