摘要: Advances in STR PCR DNA profiling technology allow for the analysis of minute quantities DNA. It is frequently possible to obtain successful results from cellular material transferred skin an individual who has simply touched object. Handling objects, such as weapons or other items associated with a crime, touching surfaces, wearing clothing, may represent sufficient contact transfer small numbers bearing cells, trace DNA, which can be successfully analyzed. With this minimal amount required yield suspect profile comes tremendous crime solving potential, and number considerations prudent application, maximization evidentiary value. Evidentiary materials not previously considered must recognized preserved, resulting type profiles interpreted their proper forensic context.
