The world of forensic DNA (deoxyribonucleic acid) has made leaps and bounds since
the forensic science's humble beginnings. The first RFLP (Restriction Fragment Length Polymorphism) analyses took
many months to obtain results. The early PCR (Polymerase Chain Reaction) systems, which include DQa, DQA1/Polymarker and D1S80,
delivered results much faster, but lacked the discriminating power. The current method of choice, STRs (Short Tandem
Repeats), combines the discriminating power of RFLP with the speed of PCR-based systems. Now, results can be delivered in
This technological advance has duly impacted the judicial system and forensic DNA analysis has become one
of most effective forensic tools in assisting the determination of both guilt and innocence.
Forensic Edge helps to navigate the complex evidence and provide clear interpretation that can guide teams to
the truth. It's understanding the code that is key. In addition, new advances such as Y Chromosome DNA Testing (Paternal
Lineage Marker) and mtDNA (Mitochondrial DNA) analysis are very useful in certain cases.
All of these technology advances have created the requirement for a deep understanding of their evidentiary value
and impact. It is critical to understand how the samples were taken, the type of DNA analysis method(s) used, and the
interpretation of the evidence in the context of the case. Karen Lawless' expertise and years of experience in DNA
