Download or read book Understanding Meiosis and Mitosis written by Stephanie Harris and published by Murphy & Moore Publishing. This book was released on 2021-11-16 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meiosis and mitosis are the processes of cell division that are studied in cell biology. Meiosis is a type of cell division that is used to produce gametes like sperm or egg cells. It is used by sexually reproducing organisms. This process includes two rounds of cell division that leads to the formation of four cells with one copy of each chromosome. Mitosis is the process in which chromosomes are replicated into two new nuclei. This results in cells that are genetically identical and which retain the same number of chromosomes. It is concerned with the transfer of parent cell's genome into two subsequent daughter cells. The processes of meiosis and mitosis differ in two aspects. These are recombination and the number of chromosomes. The topics included in this book are of utmost significance and bound to provide incredible insights to readers. Different approaches, evaluations, methodologies and studies related to this field have been included herein. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.

Book excerpt: Meiosis refers primarily to the cell division for reproduction. Meiosis, the procedure of producing gametes in preparation for sexual reproduction, has long been a focal point of concentrated research. It has been researched at the cytological, hereditary, molecular and cellular stages. Researches in model systems have exposed universal essential mechanisms while parallel studies in various organisms have led to the discovery of variations in meiotic methods. This book primarily focuses on the molecular and comparative study of meiosis via model systems. It collects various strands of examination into this enthralling and demanding field of biology.

Download or read book Meiosis written by Carol Bernstein and published by BoD – Books on Demand. This book was released on 2013-09-11 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meiosis is the key process underlying sexual reproduction in eukaryotes, occurring in single-celled eukaryotes and in most multicellular eukaryotes including animals and most plants. Thus meiosis is of considerable interest, both at the scientific level and at the level of natural human curiosity about sexual reproduction. Improved understanding of important aspects of meiosis has emerged in recent years and major questions are starting to be answered, such as: How does meiosis occur at the molecular level, How did meiosis and sex arise during evolution, What is the major adaptive function of meiosis and sex. In addition, changing perspectives on meiosis and sex have led to the question: How should meiosis be taught. This book proposes answers to these questions, with extensive supporting references to the current literature.
Download or read book Meiosis written by Bernard John and published by Cambridge University Press. This book was released on 1990-04-12 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meiosis, the antithesis of fertilization, is the unique genetically programmed mode of nuclear division associated with a halving of the chromosome number in sexually reproducing eukaryotes. It thus represents a key cellular and developmental pathway in the life of an organism. In this book, Bernard John presents the first complete, and the most authoritative, review of the events and mechanisms of meiosis including their scheduling, their mechanics and their biochemistry as well as their genetic control and the variations to be found in them in both sexual and subsexual systems. The text is superbly illustrated with 131 figures and 73 tables. Meiosis must be regarded as essential reading for all students, teachers and research workers with an interest in eukaryotic cell biology and genetics.

Download or read book Recombination and Meiosis written by Richard Egel and published by Springer Science & Business Media. This book was released on 2008-07-25 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once per life cycle, mitotic nuclear divisions are replaced by meiosis I and II – reducing chromosome number from the diploid level to a haploid genome and recombining chromosome arms by crossing-over. In animals, all this happens during formation of eggs and sperm – in yeasts before spore formation. The mechanisms of reciprocal exchange at crossover/chiasma sites are central to mainstream meiosis. To initiate the meiotic exchange of DNA, surgical cuts are made as a form of calculated damage that subsequently is repaired by homologous recombination. These key events are accompanied by ancillary provisions at the level of chromatin organization, sister chromatid cohesion and differential centromere connectivity. Great progress has been made in recent years in our understanding of these mechanisms. Questions still open primarily concern the placement of and mutual coordination between neighboring crossover events. Of overlapping significance, this book features two comprehensive treatises of enzymes involved in meiotic recombination, as well as the historical conceptualization of meiotic phenomena from genetical experiments. More specifically, these mechanisms are addressed in yeasts as unicellular model eukaryotes. Furthermore, evolutionary subjects related to meiosis are treated.

Book excerpt: In spite of the fact that the process of meiosis is fundamental to inheritance, surprisingly little is understood about how it actually occurs. There has recently been a flurry of research activity in this area and this volume summarizes the advances coming from this work. All authors are recognized and respected research scientists at the forefront of research in meiosis. Of particular interest is the emphasis in this volume on meiosis in the context of gametogenesis in higher eukaryotic organisms, backed up by chapters on meiotic mechanisms in other model organisms. The focus is on modern molecular and cytological techniques and how these have elucidated fundamental mechanisms of meiosis. Authors provide easy access to the literature for those who want to pursue topics in greater depth, but reviews are comprehensive so that this book may become a standard reference.Key Features* Comprehensive reviews that, taken together, provide up-to-date coverage of a rapidly moving field* Features new and unpublished information* Integrates research in diverse organisms to present an overview of common threads in mechanisms of meiosis* Includes thoughtful consideration of areas for future investigation

Download or read book The Meiotic System written by Bernard John and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction When the study of heredity and variation first came to be treated as a scientific subject-and this, one must remember, was only just over a hundred years ago-there was an unfortunate separation between the disciplines of cytology and experimental breeding. This separation was based partly on a lack of understanding and partly on a lack of the desire to understand. Even WILLIAM BATESON, the first apostle of mendelism in England, had a blind spot for cytology and for many years dogmatically refused to believe that MENDEL'S determinants were transmitted and distributed by the chromosomes. This separation between cytology and experimental breeding is one which persists, in a measure, even today, simply because there are two quite different, though complementary, techniques available for the study of heredity and variation. On the one hand, one can study directly the structure and behaviour of the actual vehicles which transmit the genetic determinants from one generation to the next. This is the method employed by those who study genetics through a microscope. The alternative method is that used by the experimental breeder who, in default of being able to watch the hereditary factors segregate from each other directly, is obliged to examine the constitution of the germ cells indirectly by sampling, and usually at random, the products of a controlled mating.
