Book Synopsis Organisers & Genes by : Conrad Hal Waddington
Download or read book Organisers & Genes written by Conrad Hal Waddington and published by . This book was released on 1940 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conrad Hal Waddington's Organisers and Genes, published in 1940, is a summary of available research and theoretical framework for many concepts related to tissue differentiation in the developing embryo. The book is composed of two main conceptual sections. The first section explores the action and nature of the organizer, while the second section delves into genes and their influence on development. In this book Waddington explored organizers in terms of their capacity and method of induction. First he examined the nature of induction, discussing crucial experiments concerning the organizer, including Hans Spemann's discovery of the organizer, and his own research into organizers in higher birds and mammals. Waddington separated the action of the organizer into two distinct categories, evocation and individuation, discussed below. The main experimental approach discussed in this book involved grafting organizing tissue from one embryo or region of an embryo to another. Waddington described evocation as non-assimilative induction, or a one-way inducing signal. He presented this as a chemical signal and illustrated evocation with the dead organizer experiment. The dead organizer was shown to be capable of inducing differentiation of neural tissue in the ectoderm. He also included chemical induction by estrogens and steroids as other evocative signals. An important aspect of any signal of evocation, as presented by Waddington, is that the signal is specific to the differentiation of a certain tissue type.

Download or read book Chromosomes written by Adrian T. Sumner and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrating classical knowledge of chromosome organisation with recent molecular and functional findings, this book presents an up-to-date view of chromosome organisation and function for advanced undergraduate students studying genetics. The organisation and behaviour of chromosomes is central to genetics and the equal segregation of genes and chromosomes into daughter cells at cell division is vital. This text aims to provide a clear and straightforward explanation of these complex processes. Following a brief historical introduction, the text covers the topics of cell cycle dynamics and DNA replication; mitosis and meiosis; the organisation of DNA into chromatin; the arrangement of chromosomes in interphase; euchromatin and heterochromatin; nucleolus organisers; centromeres and telomeres; lampbrush and polytene chromosomes; chromosomes and evolution; chromosomes and disease, and artificial chromosomes. Topics are illustrated with examples from a wide variety of organisms, including fungi, plants, invertebrates and vertebrates. This book will be valuable resource for plant, animal and human geneticists and cell biologists. Originally a zoologist, Adrian Sumner has spent over 25 years studying human and other mammalian chromosomes with the Medical Research Council (UK). One of the pioneers of chromosome banding, he has used electron microscopy and immunofluorescence to study chromosome organisation and function, and latterly has studied factors involved in chromosome separation at mitosis. Adrian is an Associate Editor of the journal Chromosome Research, acts as a consultant biologist and is also Chair of the Committee of the International Chromosome Conferences. The most up-to-date overview of chromosomes in all their forms. Introduces cutting-edge topics such as artificial chromosomes and studies of telomere biology.

Download or read book The Life Organic written by Erik Peterson and published by University of Pittsburgh Press. This book was released on 2016-12-23 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: As scientists debated the nature of life in the nineteenth century, two theories predominated: vitalism, which suggested that living things contained a "vital spark," and mechanism, the idea that animals and humans differed from nonliving things only in their degree of complexity. Erik Peterson tells the forgotten story of the pursuit of a Third Way in biology, known by many names, including "the organic philosophy," which gave rise to C. H. Waddington's work in the subfield of epigenetics: an alternative to standard genetics and evolutionary biology that captured the attention of notable scientists from Francis Crick to Stephen Jay Gould. The Life Organic chronicles the influential biologists, mathematicians, philosophers, and biochemists from both sides of the Atlantic who formed Joseph Needham's Theoretical Biology Club, defined and refined Third-Way thinking through the 1930s, and laid the groundwork for some of the most cutting-edge achievements in biology today. By tracing the persistence of organicism into the twenty-first century, this book also raises significant questions about how we should model the development of the discipline of biology going forward.

Book Synopsis Genetics and Evolution of the Domestic Fowl by : Lewis Stevens
Download or read book Genetics and Evolution of the Domestic Fowl written by Lewis Stevens and published by Cambridge University Press. This book was released on 1991-11-21 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of genetics has undergone a period of very rapid and significant development in recent years, and the area of poultry genetics has been no exception. This book provides a balanced and up-to-date account of all the major areas of this subject from Mendelian to modern molecular genetics. The book begins by tracing the evolution of Gallus domesticus from its avian ancestors. Subsequent chapters cover important aspects of poultry genetics, including cytogenetics, transmission genetics, gene mapping, sex linkage, lethal genes, genetics of feathering and plumage, and quantitative genetics. In each chapter, a concise explanation of the genetic principles is followed by a full discussion illustrated by key examples. In the latter part of the book, recent advances in gene cloning and sequencing are examined. The impact of these exciting new developments on our understanding of gene structure and organisation, immunogenetics and the evolution of proteins is assessed. Finally, the uses of transgenic techniques and their implications are discussed. This book provides a clear and useful survey of the genetics and evolution of the domestic fowl, which will be of interest to postgraduate students and researchers in the fields of genetics, agriculture and veterinary medicine, as well as to poultry breeders (both commercial and non-commercial).

Book Synopsis The Society of Genes by : Itai Yanai
Download or read book The Society of Genes written by Itai Yanai and published by Harvard University Press. This book was released on 2016-01-11 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly four decades ago Richard Dawkins published The Selfish Gene, famously reducing humans to “survival machines” whose sole purpose was to preserve “the selfish molecules known as genes.” How these selfish genes work together to construct the organism, however, remained a mystery. Standing atop a wealth of new research, The Society of Genes now provides a vision of how genes cooperate and compete in the struggle for life. Pioneers in the nascent field of systems biology, Itai Yanai and Martin Lercher present a compelling new framework to understand how the human genome evolved and why understanding the interactions among our genes shifts the basic paradigm of modern biology. Contrary to what Dawkins’s popular metaphor seems to imply, the genome is not made of individual genes that focus solely on their own survival. Instead, our genomes comprise a society of genes which, like human societies, is composed of members that form alliances and rivalries. In language accessible to lay readers, The Society of Genes uncovers genetic strategies of cooperation and competition at biological scales ranging from individual cells to entire species. It captures the way the genome works in cancer cells and Neanderthals, in sexual reproduction and the origin of life, always underscoring one critical point: that only by putting the interactions among genes at center stage can we appreciate the logic of life.
