What significant role does DNA play in a criminal scene and how has DNA improved in the last forty years? DNA became a standard tool for investigations in 1986 O.J. Simpson case of murder trial. In this crime scene DNA evidence was used to determine who was the killer. The blood at the crime scene clearly stated that O.J. Simpson had been the victim. O.J. Simpson crime was a very popular case and since that crime, forensics started to use DNA fingerprint’s in their investigations.
Also, DNA played a significant role after the World Trade Center attack known as 9/11. Scientist had to identity the dead bodies after the World Trade Center attack so, forensics use DNA to identify them. Even though it was over 20,000 bodies scientist had to identify and took them years. On the other hand, DNA was used find out if Bill Clinton had sexual relationship with Monica Lewinsky. How have the techniques of DNA technology revolutionized forensics? An examination of how DNA technology has …show more content…
For years’ people believed that proteins would carry the gene information and that bacterial transformation is cause by DNA. In 1945, researchers Beadle and Tatum discovered that genes basically work through the production of an enzyme. In 1953, researchers Watson and Crick, discovered the structure (double-helix structure) of the DNA. The DNA had been discovered in the late 1800s, but Watson and Crick determine the genetic inheritance which contain human genes. These two researchers found that DNA consists of four elements known as Adenine, Cytosine, Guanine, and Thymine and that DNA replicated itself. In 1961, Nirenberg and Matthaei worked on encoding the genetic code. In 1972, Berg discovered the molecular cloning of DNA and in 1977, Sanger provide information of the sequence of the nucleotides. In 1985, Jeffrey discovered the techniques of DNA fingerprinting. Berg technique is use now worldwide for police/detectives
