DNA profiling has several advantages in helping solve crimes, however, there are still disadvantages to this technique. DNA profiling can be beneficial, as well as detrimental to the society we live in. DNA profiling has become the most widely used tool in the field of forensics because of the advantages it has to offer, although there are some drawbacks when it comes to utilizing this technique. DNA profiling has greatly enhanced law enforcement investigation by helping determine the suspect in a criminal investigation, minimizing the amount of unjustified arrests, and by overturning wrongful guilty sentencing. While DNA profiling has advantages in the field of forensics, it also has disadvantages. A few of the key disadvantages of DNA profiling are easy contamination, wrongful convictions, and access to and use of data. One of the foundations in the field of forensics is the examination of DNA. DNA is the digenetic element which exists in each and every cell. Every human being has an exclusive analysis of DNA. In fact, there are even a small amount of variations among the deoxyribonucleic acid (DNA) of identical twins. DNA profiling was established in the 1980s by Sir Alec Jeffreys, a scientist from Britain. Investigators can obtain DNA for profiling from various evidence from a crime scene. DNA can be obtained from vital fluid, semen, epidermis, saliva, mucus, sweat and roots of hair. Additionally, profiling can be performed on old, as well as dried out specimens.
