The myriad ways that DNA is now used in solving crimes, medical purposes and tracing family history, makes the the benefits of DNA one of the most magnificent discoveries of the 20th century. In this essay, you will learn upon many about DNA subjects, including matching, DNA analysis, due process and inclusion versus exclusion.
DNA has come a long way, dating all the way back to the 16th century where Chinese businessmen used their thumb print as a means of access to money. In 1987, Tommie Lee Andrews, was the first man convicted by DNA evidence in a burglary and rape case. He was sentenced to 22 years in prison. In 1995, in the OJ Simpson case, one of Simpson’s defender said: “I don’t believe in DNA.” Today, DNA is one of the most indisputable …show more content…
Since 2009, more than 2,000 people have been exonerated from false convictions Forensic use of DNA technology in criminal cases began in 1986 when police asked Dr. Alec J. Jeffreys, of Leicester University in England, to verify a suspect's confession that he was responsible for two rape-murders in the English Midlands. Tests verified that the suspect had not committed the crimes. Police then began obtaining blood samples from several thousand male inhabitants in the area to identify a new suspect, In a 1987 case in England, Robert Melias became the first person convicted of a crime on the basis of DNA. DNA testing sits uneasily with other due process, simply because of the fact it focuses on factual guilt and assumes the innocent have nothing to hide. Courtrooms in the 1990’s did not take a uniform stand on DNA testing, they did, however agree that police could take hair samples from a crime scene for common law procedures and for search incident to arrest. This all changed though, when in 1985, serial killer Alan Legere, was set for his court date after his arrest. The New Brunswick Court of appeal took a more restrictive approach an claimed the police …show more content…
Age and gender are standards for participants sometimes. All these reasons help set a screening standard for potential participants in the clinical studies. Standards for each study vary very often. Exclusion - Subjects that require removal from being subjects, ie; infection, evidence of altered fitness training. Usually a person’s chances to participate in the clinical study come from their ability to safely participate, pre-existing medical conditions, and participants that may be too ill to continue. DNA Analysis: There are many test available for dna analysis such as STR “ Short Tandem Repeats” , Y-STR which is the same thing as the STR but used specifically for males Y-chromosomes usually used in sexual assault cases, Mini - STR is an alternative way to test smaller fragments of DNA. Results from the test form conclusions and tell the analyst the population genetic statistics. DNA in the process of extraction to upload: Gathering DNA:Tangible objects are any physical evidence that can connect a crime to an offender. Any type of biological evidence can be used in DNA testing, such as blood or semen is a type of tangible object but it can not always be seen by the naked eye so police use black lights to see if maybe an offender tried to clean up his tracks and not be found. Feces and vomit can also be
