The Evolution of Molecular Biology: The Search for the Secrets of Life provides the historical knowledge behind techniques founded in molecular biology, also presenting an appreciation of how, and by whom, these discoveries were made. It deals with the evolution of intellectual concepts in the context of active research in an approachable language that accommodates readers from a variety of backgrounds. Each chapter contains a prologue and epilogue to create continuity and provide a complete framework of molecular biology. This foundational work also functions as a historical and conceptual supplement to many related courses in biochemistry, biology, chemistry, genetics and history of science. In addition, the book demonstrates how the roots of discovery and advances–and an individual’s own research–have grown out of the history of the field, presenting a more complete understanding and context for scientific discovery. Expands on the development of molecular biology from the convergence of two independent disciplines, biochemistry and genetics Discusses the value of molecular biology in a variety of applications Includes research ethics and the societal implications of research Emphasizes the human aspects of research and the consequences of such advances to society

Every day it seems the media focus on yet another new development in biology--gene therapy, the human genome project, the creation of new varieties of animals and plants through genetic engineering. These possibilities have all emanated from molecular biology. A History of Molecular Biology is a complete but compact account for a general readership of the history of this revolution. Michel Morange, himself a molecular biologist, takes us from the turn-of-the-century convergence of molecular biology's two progenitors, genetics and biochemistry, to the perfection of gene splicing and cloning techniques in the 1980s. Drawing on the important work of American, English, and French historians of science, Morange describes the major discoveries--the double helix, messenger RNA, oncogenes, DNA polymerase--but also explains how and why these breakthroughs took place. The book is enlivened by mini-biographies of the founders of molecular biology: Delbrück, Watson and Crick, Monod and Jacob, Nirenberg. This ambitious history covers the story of the transformation of biology over the last one hundred years; the transformation of disciplines: biochemistry, genetics, embryology, and evolutionary biology; and, finally, the emergence of the biotechnology industry. An important contribution to the history of science, A History of Molecular Biology will also be valued by general readers for its clear explanations of the theory and practice of molecular biology today. Molecular biologists themselves will find Morange's historical perspective critical to an understanding of what is at stake in current biological research.

This book examines the toxicological and health implications of environmental epigenetics and provides knowledge through an interdisciplinary approach. Included in this volume are chapters outlining various environmental risk factors such as phthalates and dietary components, life states such as pregnancy and ageing, hormonal and metabolic considerations and specific disease risks such as cancer cardiovascular diseases and other non-communicable diseases. Environmental Epigenetics imparts integrative knowledge of the science of epigenetics and the issues raised in environmental epidemiology. This book is intended to serve both as a reference compendium on environmental epigenetics for scientists in academia, industry and laboratories and as a textbook for graduate level environmental health courses.

During the last ten years, remarkable progress has occurred in the study of molecular evolution. Among the most important factors that are responsible for this progress are the development of new statistical methods and advances in computational technology. In particular, phylogenetic analysis of DNA or protein sequences has become a powerful tool for studying molecular evolution. Along with this developing technology, the application of the new statistical and computational methods has become more complicated and there is no comprehensive volume that treats these methods in depth. Molecular Evolution and Phylogenetics fills this gap and present various statistical methods that are easily accessible to general biologists as well as biochemists, bioinformatists and graduate students. The text covers measurement of sequence divergence, construction of phylogenetic trees, statistical tests for detection of positive Darwinian selection, inference of ancestral amino acid sequences, construction of linearized trees, and analysis of allele frequency data. Emphasis is given to practical methods of data analysis, and methods can be learned by working through numerical examples using the computer program MEGA2 that is provided.

This book describes the models, methods and algorithms that are most useful for analysing the ever-increasing supply of molecular sequence data, with a view to furthering our understanding of the evolution of genes and genomes.
