DNA

DNA DNA In this report I will discuss the topic DNA and Forensics. This is an interesting topic because there have been great advances in the field of forensic science that have affected it's credibility and usage in solving crimes that would otherwise go unsolved. DNA can be found in almost any bodily fluid (semen, saliva, blood, etc.) and in less obvious places such as a strand of hair. It has become a crucial part of investigating crimes, and will continue to develop this way. DNA first came into use for forensic science in 1986. It was used by a scientist by the name of Alec Jeffrey and his colleagues from Leicester University. He was contacted by authorities to verify the confessions by a seventeen year old porter regarding a double rape-murder case. As it turns out, this boy proved to be "the first murderer to be cleared as a result of DNA fingerprinting".(Nickell and Fischer, 1998) DNA can be found in such things as blood and semen. It can also be found in such things as tissue found beneath the fingernails of a victim after a struggle, it can even be found in saliva cells left on a mouthpiece of a telephone after a conversation.
