James Watson and Francis Crick's 1953 discovery of the double helix structure of DNA is the foundation of virtually every advance in our modern understanding of genetics and molecular biology. But how did Watson and Crick do it-and why were they the ones who succeeded?In truth, the discovery of DNA's structure is the story of five towering minds in pursuit of the advancement of science, and for almost all of them, the prospect of fame and immortality: Watson, Crick, Rosalind Franklin, Maurice Wilkins, and Linus Pauling. Each was fascinating and brilliant, with strong personalities that often clashed. Howard Markel skillfully re-creates the intense intellectual journey, and fraught personal relationships, that ultimately led to a spectacular breakthrough. But it is Rosalind Franklin-fiercely determined, relentless, and an outsider at Cambridge and the University of London in the 1950s, as the lone Jewish woman among young male scientists-who becomes a focal point for Markel.The Secret of Life is a story of genius and perseverance, but also a saga of cronyism, misogyny, anti-Semitism, and misconduct. Drawing on voluminous archival research, including interviews with James Watson and with Franklin's sister, Jenifer Glynn, Markel provides a fascinating look at how science is done, how reputations are undone, and how history is written, and revised.A vibrant evocation of Cambridge in the 1950s, Markel also provides colorful depictions of Watson and Crick-their competitiveness, idiosyncrasies, and youthful immaturity-and compelling portraits of Wilkins, Pauling, and most cogently, Rosalind Franklin. The Secret of Life is a lively and sweeping narrative of this landmark discovery, one that finally gives the woman at the center of this drama her due.

This second edition provides new and updated chapters from expert researchers in the field detailing methods used to study the multi-facet deep sequencing data field. Chapters guide readers through techniques for processing RNA-seq data, microbiome analysis, deep learning methodologies, and various approaches for the identification of sequence variants. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Deep Sequencing Data Analysis: Methods and Protocols, Second Edition aims to ensure successful results in the further study of this vital field.

This detailed volume presents a comprehensive bioinformatic and experimental toolbox for prioritizing, annotating, and functionally analyzing long non-coding RNAs (lncRNAs). Playing a vital role in diverse biological progresses and human disease, lncRNAs have proven to be a challenging subject of study due to our limited understanding of their sequence-function relationships, lack of complete genetic annotation, and the unavailability of systems required to define their functional importance and molecular mechanisms, all of which this book seeks to address. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Functional Analysis of Long Non-Coding RNAs: Methods and Protocols provides atimely and convenient resource to facilitate the identification and characterization of disease-associated human lncRNAs, which aims to shed light on their role in biology and pathophysiology and ultimately lead toward novel therapeutic approaches targeting lncRNAs for the amelioration of human diseases.

Genomic selection (GS) is a promising tool in the field of breeding especially in the era where genomic data is becoming cheaper. The potential of this tool has not been realized due to its limited adaptation in various crops. Marker Assisted Selection (MAS) has been the method of choice for plant breeders while using the genomic information in the breeding pipeline. MAS, however, fails to capture vital minor gene effects while focusing only on the major genes, which is not ideal for breeding advancement especially for quantitative traits such as yield. The main aim of statistical methodologies coming under the umbrella of GS on using the whole genome information is to predict potential candidates for breeding advancement while optimizing the use of resources such as land, manpower, and most importantly time. Lack of proper understanding of the methods and their applications is one of the reasons why breeders shy away from this tool. The book is meant for biologists, especially breeders, and provides a comprehensive idea of the statistical methodologies used in GS, guidance on the choice of models, and design of datasets. The book also encourages the readers to adopt GS by demonstrating the current scenarios of these models in some of the important crops among oilseeds, vegetables, legumes, tuber crops, and cereals. For ease of implementation of GS, the book also provides hands-on scripts on GS data design and modeling in a popular open-source statistical program. Additionally, prospective in GS model development and thereby enhancement in crop improvement programs is discussed.

Genetically Modified Plants and Beyond takes a fresh look at methodologies used in developing crop plants, discusses genome editing, and interrogates the regulatory approaches that different countries are proposing to use to regulate genetically modified (GM) vs genome-edited crop plants. The book focuses on root and tuber crops, ginger, and industrial/oil seed crops. A chapter on the production of pharmaceuticals in plants is also included. Going beyond the usual debate, the book includes case studies from Africa on the adoption of GM crops.

This book brings together recent methods and theoretical approaches developed to dissect the activity and function of bacterial and eukaryotic Structural Maintenance of Chromosome (SMC) proteins. The protocols explore numerous subjects such as depletion systems to assess SMC function, genetic manipulation of SMC proteins, chromosomal, biochemical, and microscopy-based assays of SMC activity, as well as theoretical modeling of SMC activity. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, SMC Complexes: Methods and Protocols will greatly aid researchers looking into the mechanism of action of SMC complexes on DNA.Chapters 10 and 19 areavailable Open Access under a CC BY 4.0 license via link.springer.com.

Scientists are racing to unravel the code of life in our DNA sequences. But once we know the code, will we know what life means? Will we know what to do with the powerful - healing, destructive, and marketable - information we will have?Barbara Katz Rothman's warm, learned, passionate, and humorous voice is just the one we need to guide us through some of the most loaded issues and technologies of our time - ones that bear on the most intimate aspects of our lives. Her astute observations about the new genetics are combined with personal reflections: about raising a black child; the risks of cancer; midwives and pregnancy; the social web into which we are born; motherhood; time, growth, chance, and all the indefinable things that make us human. She helps us to think about the place of genetic science in our own lives, its role in our social world, and how we choose to think about human life itself.A genetic map will take us places, but we need an imagination to see the relationship between DNA and public policy, between genes and the society we live in, and to understand why human life can't be reduced to genetics. Rothman inspires that imagination, in a book that is essential reading.
