Uses case studies to examine how investigators collect genetic evidence and discusses how DNA has altered crime-solving and the court system as well as the ethical ramifications of cloning, genetic modification, and the death penalty.
Matching DNA samples from crime scenes and suspects is rapidly becoming a key source of evidence for use in our justice system. DNA Technology in Forensic Science offers recommendations for resolving crucial questions that are emerging as DNA typing becomes more widespread. The volume addresses key issues: Quality and reliability in DNA typing, including the introduction of new technologies, problems of standardization, and approaches to certification. DNA typing in the courtroom, including issues of population genetics, levels of understanding among judges and juries, and admissibility. Societal issues, such as privacy of DNA data, storage of samples and data, and the rights of defendants to quality testing technology. Combining this original volume with the new update-The Evaluation of Forensic DNA Evidence-provides the complete, up-to-date picture of this highly important and visible topic. This volume offers important guidance to anyone working with this emerging law enforcement tool: policymakers, specialists in criminal law, forensic scientists, geneticists, researchers, faculty, and students.
In 1992 the National Research Council issued DNA Technology in Forensic Science, a book that documented the state of the art in this emerging field. Recently, this volume was brought to worldwide attention in the murder trial of celebrity O. J. Simpson. The Evaluation of Forensic DNA Evidence reports on developments in population genetics and statistics since the original volume was published. The committee comments on statements in the original book that proved controversial or that have been misapplied in the courts. This volume offers recommendations for handling DNA samples, performing calculations, and other aspects of using DNA as a forensic toolâ€"modifying some recommendations presented in the 1992 volume. The update addresses two major areas: Determination of DNA profiles. The committee considers how laboratory errors (particularly false matches) can arise, how errors might be reduced, and how to take into account the fact that the error rate can never be reduced to zero. Interpretation of a finding that the DNA profile of a suspect or victim matches the evidence DNA. The committee addresses controversies in population genetics, exploring the problems that arise from the mixture of groups and subgroups in the American population and how this substructure can be accounted for in calculating frequencies. This volume examines statistical issues in interpreting frequencies as probabilities, including adjustments when a suspect is found through a database search. The committee includes a detailed discussion of what its recommendations would mean in the courtroom, with numerous case citations. By resolving several remaining issues in the evaluation of this increasingly important area of forensic evidence, this technical update will be important to forensic scientists and population geneticistsâ€"and helpful to attorneys, judges, and others who need to understand DNA and the law. Anyone working in laboratories and in the courts or anyone studying this issue should own this book.
In this new edition, the editors have thoroughly updated and dramatically expanded the number of protocols to take advantage of the newest technologies used in all branches of research and clinical medicine today. These proven methods include real time PCR, SNP analysis, nested PCR, direct PCR, and long range PCR. Among the highlights are chapters on genome profiling by SAGE, differential display and chip technologies, the amplification of whole genome DNA by random degenerate oligonucleotide PCR, and the refinement of PCR methods for the analysis of fragmented DNA from fixed tissues. Each fully tested protocol is described in step-by-step detail by an established expert in the field and includes a background introduction outlining the principle behind the technique, equipment and reagent lists, tips on trouble shooting and avoiding known pitfalls, and, where needed, a discussion of the interpretation and use of results.
Bloodstains provide clues as to how a crime had been committed. When a speck of blood falls on a surface, it leaves a shape and stain. This is called bloodstain evidence. Each individual carries DNA that is unique to him or her, except for identical twins. With the help of bloodstains and saliva, as well as fingernails, an investigator can recover enough evidence to confirm whether a defendant is guilty or innocent of a crime. This book includes sidebars that further expand on the topic, as well as a further reading list and career information for readers interested in this intriguing STEM field.
"Blood transfusion is a life-saving intervention that has an essential role in patient management within health care systems. All Member States of the World Health Organization (WHO) endorsed World Health Assembly resolutions WHA28.72 (1) in 1975 and WHA58.13 (2) in 2005. These commit them to the provision of adequate supplies of safe blood and blood products that are accessible to all patients who require transfusion either to save their lives or promote their continuing or improving health." --Preface.
Blood samples have consistently proven to be a key source of genetic material for a wide variety of diagnostic or research purposes. In DNA and RNA Profiling in Human Blood: Methods and Protocols, leading international experts contribute both established and recently developed protocols for complex and high-throughput DNA and RNA profiling. Divided into two thorough sections, the volume concentrates on DNA profiling for blood cell antigens through methods on high-throughput multiplex approaches and SNP typing, along with RNA profiling in blood cells addressing certain blood cell types such as platelets, reticulocytes, and megakaryocytes. Written in the highly successful Methods in Molecular BiologyTM series format, all of the chapters include brief introductions on the subject, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, as well as the Notes section which highlights tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, DNA and RNA Profiling in Human Blood: Methods and Protocols is an ideal guide to the molecular profiling approaches that have opened up this broad field of research and have shown great promise in the further identifying of disease markers in blood.
Blood, Bullets, and Bones provides young readers with a fresh and fascinating look at the ever-evolving science of forensics. Since the introduction of DNA testing, forensic science has been in the forefront of the public’s imagination, thanks especially to popular television shows like CSI: Crime Scene Investigation. But forensic analysis has been practiced for thousands of years. Ancient Chinese detectives studied dead bodies for signs of foul play, and in Victorian England, officials used crime scene photography and criminal profiling to investigate the Jack the Ripper murders. In the intervening decades, forensic science has evolved to use the most cutting-edge, innovative techniques and technologies. In this book, acclaimed author Bridget Heos uses real-life cases to tell the history of modern forensic science, from the first test for arsenic poisoning to fingerprinting, firearm and blood spatter analysis, DNA evidence, and all the important milestones in between. By turns captivating and shocking, Blood, Bullets, and Bones demonstrates the essential role forensic science has played in our criminal justice system.
