The use of DNA sequencing has also led to the development of new forensic techniques, such as DNA phenotyping, which allows investigators to predict an individual's physical characteristics based on their genetic data. In addition to its applications in forensic science, DNA sequencing has also been used in medical research and diagnosis.
A pair of men already serving life behind bars have been charged in two Tampa Bay-area cold case murders thanks to DNA evidence that previously helped exonerate a death row inmate.
