This introductory text provides a contextual history and overview of the science and use of DNA typing methods. Logically organized, with clear, concise language, this manual ensures a fundamental understanding of forensic DNA analysis and a thorough background of the molecular techniques used to determine an individual's identity. The experiments cover DNA extraction, concentration, and assessment; DNA analysis using restriction fragment length polymorphisms; polymerase chain reaction and PCR-based typing tests; short tandem repeat analysis; and mitochondrial DNA analysis. There is also an extensive glossary of DNA typing terminology and basic terms used in molecular biology.
