The document briefly explains the science of DNA identification analysis, rules governing the admission of DNA analysis as evidence in criminal proceedings, collection of DNA evidence in Wisconsin, and issues relating to the use of DNA evidence in Wisconsin. Two analysis techniques are most often used in forensic DNA analysis: Restriction Fragment Length Polymorphism (RFLP) and Polymerase Chain Reaction (PCR). The document describes how the two techniques work, and concludes that the major drawback to using PCR analysis is that the process is particularly susceptible to contamination. The paper examines rules of evidence applicable to DNA evidence in Federal courts and most State courts, and then considers rules and procedures specific to Wisconsin. It also describes the creation and content of the Wisconsin DNA Databank, and examines the Innocence Project. That project recommended changes in State law to improve the "truth-finding" function of the criminal justice system through the use of DNA evidence. Figures, notes
