DNA: Is it worth the risk

Introduction Deoxyribonucleic acid, also known as DNA contains genetic information and is found within the chromosome of human cells. After countless hours of research on thethis fairly new phenomenon it was Sir Alec Jeffereys of England who developed a technology that was based solely on DNA in 1985. DNA plays a major role in technology, it is used for identification, and it has been a leading source in identifying biological samples such as saliva, urine, blood, semen and hair. All of these samples have been extremely helpful with government, federal, state and even private agencies at various crime scenes. DNA can also be used to resolve disputes of paternity, and criminal cases of both present and past (cold cases). Although extremely prolific there are many issues and challenges that have to be addressed.
Although DNA exhibits profound results, there are many issues and concerns that have to be addressed. There have been numerous concerns from pillars of our communities that the database’s that withhold pertinent DNA information are not secured. Furthermore, taxpayers are concerned about the financial burden and the lack of standardization among the different laboratories will also have to be changed.

Process The first step in DNA technology is to extract DNA from a biological sample, once that sample is cut into specific sections and segments it is then arranged by the molecular size by way of using the electrophoresis process. Electrophoresis is a chemical process that separates charged molecules of a chemical mixture. In our case those molecules are DNA. Once the electrophoresis process is completed the remaining segments are labeled with probes and are exposed to radiographic film. These particular films form a characteristic pattern known as the DNA fingerprint. The term DNA fingerprint
