Forensic DNA Transfer

Forensic DNA Transfer provides a guide to the recognition and current understanding of DNA transfer in forensic criminal investigations. Increased improvements in technology mean that it is now routinely possible to obtain DNA profiles from non-visible deposits. How or when the DNA in question was deposited may be an issue in the context of the case especially if the donor of the DNA is not in dispute. A DNA profile alone cannot reveal when or how that DNA was deposited at a crime scene nor can it reveal the body matter from which it originated. Issues of transfer associated with activities may be debated—which the traditional discrimination purpose of DNA profiling cannot address. DNA may be everywhere and anywhere—in homes at workplaces during transport and on personal items including clothing. DNA from a person may be on an object they have never contacted or in a room they have never entered. Concepts discussed in the book include non-self DNA on hands through day-to-day activities the prevalence of background DNA in the environment and perhaps on the exhibit the persistence of any DNA transferred and that a DNA result will depend on these variables as well as recovery techniques. Since DNA may be transferred to an exhibit: (a) during the commission of a crime (b) before the crime and/or (c) after the crime through handling examination and testing this book covers various transfer pathways and sources of DNA. Documented cases of inadvertent transfer of DNA resulting in wrongful convictions or the misdirection of criminal investigations are discussed—with an emphasis on contamination mitigation throughout the entire process. Forensic DNA Transfer examines the additional complexity resulting from non-visible deposits of DNA that impact on sampling and testing regimes. The changing understanding of the composition of purported 'touch DNA' deposits from the skin including extracellular DNA transported via body secretions is described. Further the newer focus on interpreting DNA evidence—using activity level propositions and the rationale and associated issues—is also discussed.

Forensic DNA Applications An Interdisciplinary Perspective

Forensic DNA Applications: An Interdisciplinary Perspective Second Edition is fully updated to outline the latest advances in forensic DNA testing techniques and applications. It continues to fill the need for a reference book for people working in the field of forensic molecular biology testing and research as well as individuals investigating and adjudicating cases involving DNA evidence whether they be civil or criminal cases. DNA techniques have greatly impacted obvious traditional forensic areas but such advances have also positively affected myriad new areas of research and inquiry. It is possible today to think about solving forensic problems that were simply unheard of even a few years ago. As such the book pulls all relevant research and applied science together into a detailed and comprehensive collection. Part I begins with the history and development of DNA typing and profiling for criminal and civil purposes. It discusses the statistical interpretation of results with case examples mitochondrial DNA testing Y single nucleotide polymorphisms (SNPs) and short tandem repeats (STRs) and X SNP and STR testing. It also explores low copy number DNA typing mixtures and quality assurance and control. Part II moves on to cover the various uses and applications of analyzing collected physical evidence victim identification in mass disasters analyzing animal DNA forensic botany and other unique applications. Part III is dedicated to the latest advances and developments in human molecular biology and Part IV looks at policies and laws and ethics governing DNA evidence and its utilization in various cases and the courts. Forensic DNA Applications Second Edition covers cutting-edge research and advancements in the field and is the most up-to-date reference available. Edited and contributed to by the world's foremost leaders in the field it is a must-have reference for established professionals and an essential resource to legal professionals—lawyers and judges dealing with civil and criminal cases involving DNA technology—as well as students entering the fields of genetics and forensic DNA analysis. | Forensic DNA Applications An Interdisciplinary Perspective

Forensic DNA Analysis Current Practices and Emerging Technologies

The field of forensic DNA analysis has grown immensely in the past two decades and genotyping of biological samples is now routinely performed in human identification (HID) laboratories. Application areas include paternity testing forensic casework family lineage studies identification of human remains and DNA databasing. Forensic DNA Analysis: Current Practices and Emerging Technologies explores the fundamental principles and the application of technologies for each aspect of forensic DNA analysis. The book begins by discussing the value of DNA evidence and how to properly recognize document collect and store it. The remaining chapters examine:The most widely adopted methods and the best practices for DNA isolation from forensic biological samples and human remainsStudies carried out on the use of both messenger RNA and small (micro) RNA profilingReal-time polymerase chain reaction (PCR) methods for quantification and assessment of human DNA prior to genotypingCapillary electrophoresis (CE) as a tool for forensic DNA analysisNext-generation short tandem repeat (STR) genotyping kits for forensic applications the biological nature of STR loci and Y-chromosome STRs (Y-STRs)Mitochondrial DNA (mtDNA) sequence analysisSingle nucleotide polymorphisms (SNPs) and insertion/deletion polymorphisms (indels) in typing highly degraded DNADeep-sequencing technologiesThe current state of integrated systems in forensic DNA analysis The book concludes by discussing various aspects of sample-processing training and the entities that provide such training programs. This volume is an essential resource for students researchers teaching faculties and other professionals interested in human identification/forensic DNA analysis. | Forensic DNA Analysis Current Practices and Emerging Technologies
