Since DNA contains genetic code, much of it is studied and analyzed for a variety of reasons. It can be used for a person who is deceased, a victim of a crime or to determine one’s ethnic makeup. Even minute samples of blood, semen, saliva or a hair, can reveal the genetic identity of its owner. The nucleotide sequence is the most fundamental level of knowledge of a gene or genome. Doctors and scientists can use genetic information that can diagnose, treat, prevent and cure many illnesses and even mutation conditions. We cannot now accurately estimate the cost of the widespread use of DNA typing, but it can be expected to run into the tens of millions of dollars a year. 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. OK DNA isn't really "used." 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.
