Mutation Rate Analysis of the Human Mitochondrial D-loop and its Implications for Forensic Identity Testing

Description: To further facilitate mitochondrial DNA (mtDNA) sequence analysis for human identity testing, a better understanding of its mutation rate is needed. Prior to the middle 1990's the mutation rate applied to a forensic or evolutionary analysis was determined by phylogenetic means, This method involved calculating genetic distances as determined by amino acid or DNA sequence variability within or between species. The mutation rate as determined by this method ranged from 0.025-0.26 nucleotide subst… more

Investigation of Strategies for Improving STR Typing of Degraded and Low Copy DNA from Human Skeletal Remains and Bloodstains

Description: Forensic STR analysis is limited by the quality and quantity of DNA. Significant damage or alteration to the molecular structure of DNA by depurination, crosslinking, base modification, and strand breakage can impact typing success. Two methods that could potentially improve STR typing of challenged samples were explored: an in vitro DNA repair assay (PreCR™ Repair Mix) and whole genome amplification. Results with the repair assay showed trends of improved performance of STR profiling of blea… more
