... taking a DNA test, a person can be found guilty or not guilty. If a person claims they have been raped there can be a sperm sample taken from the suspect in order to prove that he is guilty or not. In addition, in a murder case there can be blood taken from the suspect so they can tell of his innocence. There are several ways to determine whether a person is guilty or not by this method. Many cases have begun to use this method saying that it is foolproof. People say this is the method of the future of crime scene investigation. DNA Testing is a foolproof way to prove whether a criminal is innocent or guilty. Deoxyribonucleic acid (DNA) is a chemical structure containing a base sequence. Base pairs are genetic codes made up of four chemicals (Adenine, Guanine, Cytosine and Thymine) and each sequence differs in every person. Because DNA is so complex and varies immensely in individuals, it can be used like a fingerprint, hence the name DNA Fingerprinting. DNA can be found and analyzed in blood, semen, saliva, hair and skin even if it is decades old if properly stored. The process takes longer than simple fingerprinting and is very expensive, but the results are almost perfect in determining identity. While these tests are very accurate, there is a 1 in 50 billion chance that two people will have an identical match. According to Kate Brinton and Kim-An Lieberman, the applications of DNA Fingerprinting are mainly Criminal Identification and Forensics, Paternity and Maternity tests, and Personal Identification. Many court cases have been resolved through DNA testing, and because of today’s technology, it should be used more often in all cases to minimize sending innocent people into incarceration. Before I went to a DNA laboratory, I had never imagined the experience I would have, not only personally, but from a scientific point of view. With little knowledge about the scientific aspect, what I had observed appeared to be an embryo from a human body, along with the doctor’s ability to differentiat...
