The early work carried out into the use of DNA as a method of personal identification has resulted in a progressive increase in the use of this technology to identify criminals and also to exonerate the innocent. The technology used to produce DNA profiles has changed over the years and consequently requires a new method of appraisal. This book gives a detailed insight into the way in which DNA analysis is carried out, starting with: The structure of DNA; Early attempts at personal identification, such as fingerprints; How DNA is analysed; The creation of DNA databases; Ethical considerations. The second edition of Genetics DNA Technology: Legal Aspects maintains the original idea of a book that is aimed at professional lawyers. It is not intended as a textbook of law, but as an adjunct to those who are studying law or want to become forensic scientists. This book is intended as a resource for lawyers, at all levels, from students to barristers and beyond. All those that deal with DNA within the law need to have some grip on the way it is used. It is not just how it is collected, nor how the analysis is carried out, but how it is used in court. This covers all of the uses, both correct and incorrect, of DNA in court. DNA is a most powerful tool in personal identification, but we must be aware of how it is used and not be dazzled by it. With a comprehensive glossary and analysis of the statistical use of DNA this book should be a valuable resource for all those invoved, or just interested, in the way in which DNA is used in court.
