Misuse of desoxyribonucleic acid in Homicide Cases - Dissertation ExampleLaw enforcers and the arbiter system had a breakthrough when deoxyribonucleic acid indite was discovered and applied in law enforcement. This rule was deemed more effective than other modes in terms of accuracy and efficiency. This is because it was difficult to disprove deoxyribonucleic acid, evidence since it places an person in the scene of the crime. Fingerprints were equally effective, but they ar easier to be corrupted and offenders have become learned with time, for example, they do not leave fingerprints behind in crime scenes. DNA, however, is hard to be corrupted, and it is difficult for and item-by-item to conceal it, since DNA is present in tissues and fluids in the body of a person. Krude (2004) shows how DNA has changed the society and light since mitochondria DNA can be obtained from bones and teeth of an individual. Hypothesis Like any other breakthrough, on that point have been contr oversies, which have been raised regarding the misuse of DNA especially in homicide case, despite the fact that DNA of an individual is unique and could not match with others individuals and law enforcement have misused the technology. info Source and order of Collection The data collected through holding surveys, which involved doing personal interviews on DNA specialist. Data was also collected through extensive research on existing writings discussing the subject. Variables We had two defendant variables, defensive and retaliatory violence. Defensive violence was measured through bring uping two scenarios that involved Method of synopsis In the analysis process, statistical information including graphs and figures were employed and were cross referenced with the information in the literature on DNA in law enforcement. Major findings DNA Sequencing The data collected by Culliford (1994), DNA refers to the genetic instructions vital for the function and development of all liv ing organisms. DNA is unique in each personage with the exclusion of monozygotic twins. DNA profiling, however, is the practice commonly employed by forensic scientists to make out the identity of individuals using their DNA profiles. I believe that these profiles are number sets that are encrypted to reflect an individuals genetic makeup. This identification method is commonly employed in sinful investigations and paternity tests. This is effective since 99.9% of sequences in human DNA are dissimilar with the exception of monozygotic twins. It is life-or-death for one to understand the concept of DNA technologies in order to have a better sagacity on the use of DNA in criminology. History of DNA Profiling According to The technique of DNA, profiling was initially reported in 1984 at the University of Leister. This was through sir Alec Jefferys, a British geneticist who developed a method of DNA fingerprinting and profiling. It is evident that the scientist made this crucial disc overy while observing the image of a DNA in an x-ray film. This image showed evidence of some similarities and distinctions in DNA. He used samples of DNA from the different family members of his staff. This enabled him to determine a scope through which DNA fingerprinting could be used to identify individuals using this method. Despite the method being discovered in 1984, it was made commercially available tether years later. In the article,
