DNA in the Forensic Science Community Essay -- Biology, DNA collection

This paper explores deoxyribonucleic acid (DNA) collection and its relationship to solving crimes. The collection of DNA is one of the most important steps in identifying a suspect in a crime. DNA evidence can either convict or exonerate an individual of a crime. Furthermore, the accuracy of forensic identification of evidence has the possibility of leaving biased effects on a juror (Carrell, Krauss, Liberman, Miethe, 2008). This paper examines Carrells et al’s research along with three other research articles to review how DNA is collected, the effects that is has on a juror and the pros and cons of DNA collection in the Forensic Science and Criminal Justice community. Keywords: deoxyribonucleic acid, United States DNA Collection in the Forensic Science Community and its Effects on Solving Crimes Once a crime has been committed the most important item to recover is any type of evidence left at the scene. If the suspect left any Deoxyribonucleic acid (DNA) at the crime scene, he could then be linked to the crime and eventually charged. A suspect’s DNA can be recovered if the suspect leaves a sample of his or her DNA at the crime scene. However, this method was not always used to track down a suspect. Not too long ago, detectives used to use bite marks, blood stain detection, blood grouping as the primary tool to identify a suspect. DNA can be left or collected from the hair, saliva, blood, mucus, semen, urine, fecal matter, and even the bones. DNA analysis has been the most recent technique employed by the forensic science community to identify a suspect or victim since the use of fingerprinting. Moreover, since the introduction of this new technique it has been a la... ...race, class and gender differences. In addition, to the inequality, methods of presenting DNA data is sometimes sloppy and has the scrutiny of being dismissed on the grounds of misleading or confusing evidence. Also, the errors in the forensic science community play a role in the high number of exoneration cases because of false identification. Since DNA technology has been used there has been a high number of individuals convicted, linked or found innocent of a crimes. This technology has helped law enforcement catch suspects that may have never been found without the use of this technology. However, the research reflected that there is a need for clearer interpretations of the DNA results, better equality provided for all regardless of race or class and that errors should be reduced to prevent having cases that need to be exonerated.
