Penn State University: Penn State team to triple size of forensic database of mitochondrial DNA

Penn State University: Penn State team to triple size of forensic database of mitochondrial DNA. “In circumstances where potential crime scene evidence such as hair or bone might be old or degraded, forensic scientists rely on DNA from a cell’s mitochondria — an organelle that has its own genome separate from the ‘human genome’ in the cell’s nucleus. Now, the National Institute of Justice has awarded a team of researchers from Penn State $770,000 to sequence the mitochondrial genomes of 10,000 Pennsylvanians. This will more than triple the size of the existing database and provide a crucial point of reference for use in human identification cases.”
