DNA ANALYSIS

Specialty Definition: DNA testing

(From Wikipedia, the free Encyclopedia)

DNA testing is a modern forensic procedure wherein a subject's DNA is collected (usually by taking a saliva sample, but also often from other tissues) and then compared to a known sample. It is useful in such cases as determining paternity and solving complex genealogical issues. It is perhaps best known in the field of criminal investigation, where it has recently been used to exonerate people who have been convicted of certain crimes; it is also frequently used as prosecutorial evidence, for example to show that a suspect was at the scene of a crime. DNA testing has also been used to generate hypotheses on the pattern of the human diaspora in prehistoric times.
In June of 2003, because of new DNA evidence, Dennis Halstead, John Kogut and John Restivo won a re-trial on their murder conviction. The three men had already served 18 years of their 30-plus year sentences.
