Forensic DNA and Ancient DNA
Since the discovery of techniques that allow for DNA analysis and sequencing, not only did it impact the field of genomics, but it also stimulated other fields of applications. (Capelli et al, 2003). Two unconventional and ways of applying these techniques, ancient DNA (aDNA) analysis and forensic DNA profiling (Capelli et al, 2003), are branches of this discovery that intertwine in respect to their methodologies and approaches. In this commentary, I will attempt to analyze the criteria of authentication, the different aspects of the purpose of DNA analysis, and the problems regarding contamination of the two unconventional applications of DNA analysis.
DNA analysis has become an effective procedure in forensic genetics. Prior to 1985, the methods of analyzing biological samples were limited to only conventional blood group and enzyme analysis in criminal cases (Capelli et al, 2003). These methods were informing but nevertheless only gave surface analysis. The advent of the polymerase chain reaction (PCR) changed this phenomena and made DNA analysis an endless scope applicability. Capelli et al states that it allowed forensic experts to address the most inaccessible sources of DNA evidences (such as cigarette butts, fingerprints etc. which are predominant in criminal cases) On the side of ancient DNA analysis, it provided opportunities for scientists to 'go back in time' and study the genetic relationships of extinct organisms to their contemporary relatives. (Holfeiter et al, 2001).
