The story of modern forensic DNA methodology is one of moving from simple identification to solving "impossible" cases using highly specialized laboratory techniques. 1. The Foundation: Collection and Extraction
The breakthrough in modern forensic science is the . This methodology acts like a molecular Xerox machine, taking tiny or degraded samples and "amplifying" them into millions of copies. This allows scientists to analyze evidence that was previously too small or old to be tested. 3. The Blueprint: STR Loci and Electrophoresis DNA Profiling in Forensic Science: A Review - PMC - NIH
Every forensic story begins at the crime scene. Analysts must carefully collect biological evidence—like (often called "touch DNA"). The first hurdle is extracting usable DNA from complex or contaminated surfaces, followed by quantitation to ensure there is enough material for a reliable profile. 2. The Engine: PCR Amplification
