Forensic DNA Analysis Current Practices and Emerging Technologies

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

Introduction to Forensic DNA Evidence for Criminal Justice Professionals

Introduction to Forensic DNA Evidence for Criminal Justice Professionals

The use of DNA profiling in forensic cases has been considered the most innovative technique in forensic science since fingerprinting yet for those with limited scientific knowledge understanding DNA enough to utilize it properly can be a daunting task. Introduction to Forensic DNA Evidence for Criminal Justice Professionals is designed for nonscientific readers who need to learn how to effectively use forensic DNA in criminal cases. Written by a forensic scientist world renowned for her expertise in clothing examination the book provides a balanced perspective on the weight of DNA evidence. Going beyond a simple explanation of the methodology it arms attorneys and other criminal justice professionals with knowledge of the strengths and limitations of the evidence including the danger in relying on DNA statistical probabilities in the determination of guilt. The book covers the most common DNA methods used in criminal trials today nuclear DNA short tandem repeat (STR) techniques mitochondrial DNA and Y-STR profiling. It helps prosecutors know when to emphasize DNA evidence or proceed with trial in the absence of such evidence. It assists defense lawyers in knowing when to challenge DNA evidence and perhaps employ an independent expert when to focus elsewhere or when to secure the advantage of an early guilty plea. By imparting practical and theoretical knowledge in an accessible manner the book demystifies the topic to help both sides of the adversarial system understand where DNA evidence fits within the context of the case.

Forensic DNA Transfer

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.
