Book Description
The problem of unraveling two intertwined strands during the duplication of DNA was recognized shortly after the proposal of the DNA double helix structure in 1953. A group of enzymes called DNA topoisomerases solve this problem by breaking and rejoining DNA molecules in a controlled manner, thereby allowing strands to be passed through each other and thus untangled—not just during DNA replication, but also during many other basic cellular processes. Because of their intimate involvement in the workings of the cell, topoisomerases are also the logical targets of many antibiotics (including Cipro) and anticancer agents. This book, written by James Wang, the discoverer of the first topoisomerase and a leader in the field since, presents ten chapters covering the historical backdrop of the DNA entanglement problem and the discovery of the DNA topoisomerases, how DNA topoisomerases perform their magic in DNA replication, transcription, genetic recombination and chromosome condensation, and how they are targets of therapeutic agents. The book should appeal to readers from undergraduates upwards with interests in the biological and clinical aspects of topoisomerase function, or in the mathematics and physics of topology.

Book Description
Scientists and philosophers have long struggled to answer the questions of when human life begins and when human life has inherent value. The phenomenon of identical (monozygotic) twinning presents a significant challenge to the view that human life and human personhood begin at conception. The fact that a single embryo can split to generate two (or more) genetically identical embryos seems to defy the notion that prior to splitting an embryo can be a single human individual. In Untangling Twinning, Maureen Condic looks at the questions raised by human twinning based on a unique synthesis of molecular developmental biology and Aristotelian philosophy. She begins with a brief historical analysis of the current scientific perspective on the embryo and proceeds to address the major philosophic and scientific concerns regarding human twinning and embryo fusion: Is the embryo one human or two (or even more)? Does the original embryo die, and if not, which of the twins is the original? Who are the parents of the twins? What do twins, chimeras, cloning, and asexual reproduction in humans mean? And what does the science of human embryology say about human ensoulment, human individuality, and human value? Condic's original approach makes a unique contribution to the discussion of human value and human individuality, and offers a clear, evidence-based resolution to questions raised by human twinning. The book is written for students and scholars of bioethics, scientists, theologians, and attorneys who are involved in questions surrounding the human embryo.

Book Description
Complex Systems are natural systems that science is unable to describe exhaustively. Examples of Complex Systems are both unicellular and multicellular living beings; human brains; human immune systems; ecosystems; human societies; the global economy; the climate and geology of our planet. This book is an account of a marvelous interdisciplinary journey the author made to understand properties of the Complex Systems. He has undertaken his trip, equipped with the fundamental principles of physical chemistry, in particular, the Second Law of Thermodynamics that describes the spontaneous evolution of our universe, and the tools of Non-linear dynamics. By dealing with many disciplines, in particular, chemistry, biology, physics, economy, and philosophy, the author demonstrates that Complex Systems are intertwined networks, working in out-of-equilibrium conditions, which exhibit emergent properties, such as self-organization phenomena and chaotic behaviors in time and space.

Book Description
The explosion of the field of genetics over the last decade, with the new technologies that have stimulated research, suggests that a new sort of reference work is needed to keep pace with such a fast-moving and interdisciplinary field. Brenner's Encyclopedia of Genetics, Second Edition, Seven Volume Set, builds on the foundation of the first edition by addressing many of the key subfields of genetics that were just in their infancy when the first edition was published. The currency and accessibility of this foundational content will be unrivalled, making this work useful for scientists and non-scientists alike. Featuring relatively short entries on genetics topics written by experts in that topic, Brenner's Encyclopedia of Genetics, Second Edition, Seven Volume Set provides an effective way to quickly learn about any aspect of genetics, from Abortive Transduction to Zygotes. Adding to its utility, the work provides short entries that briefly define key terms, and a guide to additional reading and relevant websites for further study. Many of the entries include figures to explain difficult concepts. Key terms in related areas such as biochemistry, cell, and molecular biology are also included, and there are entries that describe historical figures in genetics, providing insights into their careers and discoveries. This 7-volume set represents a 25% expansion from the first edition, with over 1600 articles encompassing this burgeoning field Thoroughly up-to-date, with many new topics and subfields covered that were in their infancy or not inexistence at the time of the first edition. Timely coverage of emergent areas such as epigenetics, personalized genomic medicine, pharmacogenetics, and genetic enhancement technologies Interdisciplinary and global in its outlook, as befits the field of genetics Brief articles, written by experts in the field, which not only discuss, define, and explain key elements of the field, but also provide definition of key terms, suggestions for further reading, and biographical sketches of the key people in the history of genetics

Book Description
Double Helix History examines the interface between genetics and history in order to investigate the plausibility of ‘new’ knowledge derived from scientific methods and to reflect upon what it might mean for the practice of history. Since the mapping of the human genome in 2001, there has been an expansion in the use of genetic information for historical investigation. Geneticists are confident that this has changed the way we know the past. This book considers the practicalities and implications of this seemingly new way of understanding the human past using genetics. It provides the first sustained engagement with these so-called ‘genomic histories’. The book investigates the ways that genetic awareness and practice is seemingly changing historical practice and conceptualisation. Linking six concepts – ‘Public’, ‘Practice’, ‘Ethics’, ‘Politics’, ‘Self’, and ‘Imagination – Double Helix History outlines the ways that genetic information, being postgenomic, the public life of DNA, and the genetic historical imaginary work on the body, on collective memory, on the historical imagination, on the ethics of historical investigation, on the articulation of history, and on the collection and interpretation of data regarding the ‘past’. This book will appeal to researchers and students alike interested in DNA, genetics, and historiography.

Book Description
Replicating and Repairing the Genome provides a concise overview of the fields of DNA replication and repair. The book is particularly appropriate for graduate students and advanced undergraduates, and scientists entering the field or working in related fields. The breadth of information regarding DNA replication and repair is vast and often difficult to absorb, with terminology that differs between experimental systems and with complex interconnections of these processes with other cellular pathways. This book provides simple conceptual descriptions of replication and repair pathways using mostly generic protein names, laying out the logic for how the pathways function and highlighting fascinating aspects of the underlying biochemical mechanisms and biology. The book incorporates extensive and informative diagrams and figures, as well as descriptions of a number of carefully chosen experiments that had major influences in the field.The process of DNA replication is explained progressively by starting with the system of a simple bacterial virus that uses only a few proteins, followed by the well-understood bacterial (E coli) system, and then culminating with the more complex eukaryotic systems. In the second half of the book, individual chapters cover key areas of DNA repair — postreplication repair of mismatches and incorporated ribonucleotides, direct damage reversal, excision repair, and DNA break repair, as well as the related areas of DNA damage tolerance (including translesion DNA polymerases) and DNA damage responses. The book closes with chapters that describe the huge impact of DNA replication and repair on aspects of human health and on modern biotechnology.
