Sequencing is often associated with the Human Genome Project and celebrated achievements concerning the DNA molecule. However, the history of this practice comprises not only academic biology, but also the world of computer-assisted information management. The book uncovers this history, qualifying the hype and expectations around genomics.

Using genome sequencing, one can predict possible interactions among proteins. There are very few titles that focus on protein-protein interaction predictions in bacteria. The authors will describe these methods and further highlight its use to predict various biological pathways and complexity of the cellular response to various environmental conditions. Topics include analysis of complex genome-scale protein-protein interaction networks, effects of reference genome selection on prediction accuracy, and genome sequence templates to predict protein function.

Quantitative trait locus (QTL) mapping is used to discover the genetic and molecular architecture underlying complex quantitative traits. It has important applications in agricultural, evolutionary, and biomedical research. R/qtl is an extensible, interactive environment for QTL mapping in experimental crosses. It is implemented as a package for the widely used open source statistical software R and contains a diverse array of QTL mapping methods, diagnostic tools for ensuring high-quality data, and facilities for the fit and exploration of multiple-QTL models, including QTL x QTL and QTL x environment interactions. This book is a comprehensive guide to the practice of QTL mapping and the use of R/qtl, including study design, data import and simulation, data diagnostics, interval mapping and generalizations, two-dimensional genome scans, and the consideration of complex multiple-QTL models. Two moderately challenging case studies illustrate QTL analysis in its entirety.

The book alternates between QTL mapping theory and examples illustrating the use of R/qtl. Novice readers will find detailed explanations of the important statistical concepts and, through the extensive software illustrations, will be able to apply these concepts in their own research. Experienced readers will find details on the underlying algorithms and the implementation of extensions to R/qtl. There are 150 figures, including 90 in full color.

A thought-provoking exploration of deleterious mutations in the human genome and their effects on human health and wellbeing Despite all of the elaborate mechanisms that a cell employs to handle its DNA with the utmost care, a newborn human carries about 100 new mutations, originated in their parents, about 10 of which are deleterious. A mutation replacing just one of the more than three billion nucleotides in the human genome may lead to synthesis of a dysfunctional protein, and this can be inconsistent with life or cause a tragic disease. Several percent of even young people suffer from diseases that are caused, exclusively or primarily, by pre ]existing and new mutations in their genomes, including both a wide variety of genetically simple Mendelian diseases and diverse complex diseases such as birth anomalies, diabetes, and schizophrenia. Milder, but still substantial, negative effects of mutations are even more pervasive. As of now, we possess no means of reducing the rate at which mutations appear spontaneously. However, the recent flood of genomic data made possible by next-generation methods of DNA sequencing, enabled scientists to explore the impacts of deleterious mutations on humans with previously unattainable precision and begin to develop approaches to managing them. Written by a leading researcher in the field of evolutionary genetics, Crumbling Genome reviews the current state of knowledge about deleterious mutations and their effects on humans for those in the biological sciences and medicine, as well as for readers with only a general scientific literacy and an interest in human genetics. * Provides an extensive introduction to the fundamentals of evolutionary genetics with an emphasis on mutation and selection * Discusses the effects of pre-existing and new mutations on human genotypes and phenotypes * Provides a comprehensive review of the current state of knowledge in the field and considers crucial unsolved problems * Explores key ethical, scientific, and social issues likely to become relevant in the near future as the modification of human germline genotypes becomes technically feasible Crumbling Genome is must-reading for students and professionals in human genetics, genomics, bioinformatics, evolutionary biology, and biological anthropology. It is certain to have great appeal among all those with an interest in the links between genetics and evolution and how they are likely to influence the future of human health, medicine, and society.

Aging has long since been ascribed to the gradual accumulation of DNA mutations in the genome of somatic cells. However, it is only recently that the necessary sophisticated technology has been developed to begin testing this theory and its consequences. Vijg critically reviews the concept of genomic instability as a possible universal cause of aging in the context of a new, holistic understanding of genome functioning in complex organisms resulting from recent advances in functional genomics and systems biology. It provides an up-to-date synthesis of current research, as well as a look ahead to the design of strategies to retard or reverse the deleterious effects of aging. This is particularly important in a time when we are urgently trying to unravel the genetic component of aging-related diseases. Moreover, there is a growing public recognition of the imperative of understanding more about the underlying biology of aging, driven by continuing demographic change.

The book serves as a guide for potential users in developing countries and for scientists who may wish to work abroad. In addition, the low-cost approach outlined in this book can be useful for high school, undergraduate, or continuing education programs.

Epigenetics is the study of heritable changes in gene function that do not involve changes in the DNA sequence. These changes, consisting principally of DNA methylation, histone modifications, and non-coding RNAs, maintain or modulate the initial impact of regulatory factors that recognize and associate with particular genomic sequences. Epigenetic modifications are manifest in all aspects of normal cellular differentiation and function, but they can also have damaging effects that result in pathologies such as cancer. Research is continuously uncovering the role of epigenetics in a variety of human disorders, providing new avenues for therapeutic interventions and advances in regenerative medicine. This book's primary goal is to establish a framework that can be used to understand the basis of epigenetic regulation and to appreciate both its derivation from genetics and interdependence with genetic mechanisms. A further aim is to highlight the role played by the three-dimensional organization of the genetic material itself (the complex of DNA, histones and non-histone proteins referred to as chromatin), and its distribution within a functionally compartmentalized nucleus. This architectural organization of the genome plays a major role in the subsequent retrieval, interpretation, and execution of both genetic and epigenetic information.

DNA fingerprinting is a revolutionary technique that enables scientists to match minute tissue samples and facilitates scientific studies on the composition, reproduction, and evolution of animal and plant populations. As a tool for positive identification of criminals, it plays a particularly important role in forensic science. The first book to be published in the field, , DNA Fingerprinting is a practical guide to basic principles and laboratory methods as applied to a variety of fields including forensic analysis, paternity testing, medical diagnostics, animal and plant sciences, and wildlife poaching.

For decades after the identification of the structure of DNA, scientists focused only on genes, the regions of the genome that contain codes for the production of proteins. Other regions that make up 98 percent of the human genome were dismissed as "junk," sequences that serve no purpose. But researchers have recently discovered variations and modulations in this junk DNA that are involved with a number of intractable diseases. Our increasing knowledge of junk DNA has led to innovative research and treatment approaches that may finally ameliorate some of these conditions. Junk DNA can play vital and unanticipated roles in the control of gene expression, from fine-tuning individual genes to switching off entire chromosomes. These functions have forced scientists to revisit the very meaning of the word "gene" and have engendered a spirited scientific battle over whether or not this genomic "nonsense" is the source of human biological complexity. Drawing on her experience with leading scientific investigators in Europe and North America, Nessa Carey provides a clear and compelling introduction to junk DNA and its critical involvement in phenomena as diverse as genetic diseases, viral infections, sex determination in mammals, and evolution. We are only now unlocking the secrets of junk DNA, and Nessa Carey's book is an essential resource for navigating the history and controversies of this fast-growing, hotly disputed field.

RNA interference (RNAi) has the potential to make major contributions towards sustainable crop production and protection with minimal environmental impacts compared to other technologies. RNAi is being developed and exploited both within plants (i.e. host-induced gene silencing, HIGS) and/or as topical applications (e.g. spray-induced gene silencing, SIGS) for targeting pest and pathogen genes and for manipulating endogenous gene expression in plants. Chapters by international experts review current knowledge on RNAi, methods for developing RNAi systems in GM plants and applications for crop improvement, crop production and crop protection. Chapters examine both endogenous systems in GM plants and exogenous systems where interfering RNAs are applied to target plants, pests and pathogens. The biosafety of these different systems is examined and methods for risk assessment for food, feed and environmental safety are discussed. Finally, aspects of the regulation of technologies exploiting RNAi and the socio-economic impacts of RNAi technologies are discussed.

Epigenetics is the most exciting field in biology today, developing our understanding of how and why we inherit certain traits, develop diseases and age, and evolve as a species. This non-fiction comic book introduces us to genetics, cell biology and the fascinating science of epigenetics, which is rapidly filling in the gaps in our knowledge, allowing us to make huge advances in medicine. We'll look at what identical twins can teach us about the epigenetic effects of our environment and experiences, why certain genes are 'switched on' or off at various stages of embryonic development, and how scientists have reversed the specialization of cells to clone frogs from a single gut cell. In Introducing Epigenetics, Cath Ennis and Oliver Pugh pull apart the double helix, examining how the epigenetic building blocks and messengers that interpret and edit our genes help to make us, well, us.

Written primarily for students embarking on an undergraduate bioscience degree, this primer will review the essential biological concepts that underpin any programme of more advanced study and give early-stage undergraduates the opportunity to review topics about which they may feel under-prepared or less confident. Genetic medicine has entered an era of rapid expansion. It is no longer just relevant to families affected by rare congenital disorders, but has the potential to affect the diagnosis and treatment of most common complex diseases. The successful application of new genetic science in the decades ahead will depend on the next generation of undergraduates or university applicants, who are now planning their careers as Biologists and Clinicians.This primer explores core concepts about heredity and genome analysis, illustrates current clinical practice with case-histories, and discusses the potentials and pitfalls of personalised medicine.

Synthetic biology is one of the 21st century's fastest growing fields of research, as important for technology as for basic science. Building on traditional genetic engineering, which was restricted to changing one or two genes, synthetic biology uses multi-gene modules and pathways to make very significant changes to what cells can do. Synthetic biologists aim to have an impact in fields as diverse as drug manufacture, biofuel production, tackling pollution, and medical diagnostics. Further ahead, synthetic biology may even make possible the long-standing goal of creating new life from non-living starting materials. This Very Short Introduction provides a concise explanation of what synthetic biology is, and how it is beginning to affect many fields of technology. Jamie Davies also discusses the considerable controversies surrounding synthetic biology, from questions over the assumption that engineering concepts can be applied to living systems easily, to scepticism over the claims for commercial promise, fears that the dangers of engineering life are worse than its benefits, and concerns over whether humans should be designing living systems at all. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

This is an introductory text and laboratory manual to be used primarily in undergraduate courses. It is also useful for graduate students and research scientists who require an introduction to the theory and methods of nanopore sequencing. The book has clear explanations of the principles of this emerging technology, together with instructional material written by experts that describes how to use a MinION nanopore instrument for sequencing in research or the classroom.At Harvard University the book serves as a textbook and lab manual for a university laboratory course designed to intensify the intellectual experience of incoming undergraduates while exploring biology as a field of concentration. Nanopore sequencing is an ideal topic as a path to encourage students about the range of courses they will take in Biology by pre-emptively addressing the complaint about having to take a course in Physics or Maths while majoring in Biology. The book addresses this complaint by concretely demonstrating the range of topics - from electricity to biochemistry, protein structure, molecular engineering, and informatics - that a student will have to master in subsequent courses if he or she is to become a scientist who truly understands what his or her biology instrument is measuring when investigating biological phenomena.

Quick, who won the Nobel Prize for discovering the double helical structure of DNA? Most people would say Watson and Crick. But most people would make Maurice Wilkins very upset. The Rodney Dangerfield of biology, Wilkins shared the prize with Watson and Crick but missed out on the limelight, due largely to Watson's hit book, The Double Helix. Wilkins thought the book was so misleading he asked Harvard University Press not to publish it. Things have quieted down a bit now, and Wilkins is now telling the story his way. This book tells how he showed his colleagues the x-ray picture that gave them their crucial insight, and about his interactions with Rosalind Franklin, the researcher who actually created the picture, and who also received very little credit for her role in the discovery. This year marks the 50th anniversary of the DNA discovery. Finally Wilkins gets to have his say.

Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water, feces, or air) without the prior isolation of any target organism. The analysis of environmental DNA has the potential of providing high-throughput information on taxa and functional genes in a given environment, and is easily amenable to the study of both aquatic and terrestrial ecosystems. It can provide an understanding of past or present biological communities as well as their trophic relationships, and can thus offer useful insights into ecosystem functioning. There is now a rapidly-growing interest amongst biologists in applying analysis of environmental DNA to their own research. However, good practices and protocols dealing with environmental DNA are currently widely dispersed across numerous papers, with many of them presenting only preliminary results and using a diversity of methods. In this context, the principal objective of this practical handbook is to provide biologists (both students and researchers) with the scientific background necessary to assist with the understanding and implementation of best practices and analyses based on environmental DNA.

This book is the first to approach the fast developing field of wildlife forensics with a focus on the application of DNA profiling and analysis. Case studies throughout link theory and practice and highlight the use of DNA testing in species testing. The text assumes only a basic background knowledge of DNA, so offers information boxes clarifying technical information, step-by-step guidance on sequence comparisons, and a discussion of the different markers used in species testing. This produces a highly accessible introduction for both students and forensic professionals.

DNA can be extracted and sequenced from a diverse range of biological samples, providing a vast amount of information about evolution and ecology. The analysis of DNA sequences contributes to evolutionary biology at all levels, from dating the origin of the biological kingdoms to untangling family relationships. An Introduction to Molecular Evolution and Phylogenetics presents the fundamental concepts and intellectual tools you need to understand how the genome records information about evolutionary past and processes, how that information can be "read", and what kinds of questions we can use that information to answer. Starting with evolutionary principles, and illustrated throughout with biological examples, it is the perfect starting point on the journey to an understanding of the way molecular data is used in modern biology.
