Book Description
During the past twenty years the structure of the nuclear envelope, and in particular, that of its most distinct elements, the nuclear pore complexes, has been described from thin section electron microscopy (e, g., Brettschneider, 1952; Hartmann, 1953; Bahr and Beermann, 1954; Watson, 1954; Kautz and de Marsh, 1955; Watson, 1955), from metal-shadowed (e. g., Callan and Tomlin, 1950; Gall, 1954, 1956) and negatively stained (e. g., Franke, 1966, 1967; Gall, 1967; Yoo and Bayley, 1967) preparations of isolated nuclear membranes as revealing characte ristics common to euka. ryotic cells in general (recently reviewed, e. g., in Gouran ton, 1969; Stevens and Andre, 1969; Franke, 1970). In the recent years the freeze-etch technique (Steere, 1957) has proved to be a particularly useful tool in studying membraneous structures (e. g., Moor and Miihlethaler, 1963; Branton and Moor, 1964; Branton, 1966; Koehler, 1968b; Staehelin, l968a; Northcote, 1968a; Branton, 1969; Moor, 1969a). So this method has especially broadened the knowledge, e. g., on bacterial membranes (Bayer and Remsen, 1970; Nanninga, 1970), on erythrocyte plasma membranes (Weinstein and Bullivant, 1967; Meyer and Winkelmann, 1970; da Silva and Branton, 1970; Tillack and Marchesi, 1970), on liver cell membranes (Chalcroft and Bullivant, 1970), on Golgi membranes (Werz and Kellner, 1970; Staehelin and Kiermayer, 1970), on synaptic vesicles (Moor et al.

Book Description
Aspects of Nuclear Structure and Function deals with various aspects of nuclear structure and function and covers topics ranging from the ultrastructure of the female gamete to the structure, biochemistry, and functions of the nuclear envelope. Banding patterns in chromosomes, histones and nonhistone proteins, and the transfer of genetic information in polytene cells are also discussed. This book is comprised of six chapters and begins by presenting a comparative view of some aspects of the ultrastructure of the vegetative (growth) aspects of oogenesis, with emphasis on microtubules, intercellular bridges of differentiating oocytes, and vitellogenesis as well as accessory structures of the egg envelope. The following chapters explore the structure, biochemistry, and functions of the nuclear envelope; banding patterns in chromosomes; chromosomal proteins (histones and nonhistone proteins); transfer of genetic information in polytene cells; and the intracellular biology of DNA polymerases in eukaryotic cells, their association with the nucleus, and how this association changes during the mitotic cell cycle. The relationship between eukaryotic DNA polymerases and DNA replication is also examined. This monograph should be a valuable resource for biochemists.

Book Description
Advances in the development and application of electron microscopic techniques have occurred recently such that the electron microscope has evolved to become an essential tool in both basic and clinical research. Use of this instrument has contributed significantly to the formation of new perspectives and concepts concerning cell fine structure. These structural perspectives are now being integrated with specific functional, biochemical and pathophysiological events and processes of cells and tissues. Most recently, utilization of innovative electron microscopic techniques such as freeze-fracture, freeze etching, and scanning and high-voltage electron microscopy offers both the basic and clinical scientist potentially fundamental insights into many morphodynamic processes related to the activities of cells and tissues. Such an approach has been especially rewarding when applied to the dynamic events of gametogenesis and early embryonic development. The chapters comprising this book have been selected and edited with the aim of providing an up-to-date and comprehensive account of the most important aspects of vertebrate gamets and embryos as revealed by the integration of several different submicroscopic methods. The organization of the chapters is designed to indicate present gaps in our knowledge of the developmental and reproductive biology of gametes and the developing embryo and possible Iines of research which may lead to a lessening of these gaps.

Book Description
This book launches a new continuing series in developmental biology. Any new publishing venture in science can only be justified if it satisfies a need and fulfills that need in an exemplary way. I believe that there is an acute need for comprehensive treatises on specialized topics in developmental biology-especially because this is a very diverse field that receives con tributions from a wide variety of disciplines. It is difficult to remain abreast of progress in multifaceted topics and to understand how the various aspects of a topic interrelate. The volumes that will comprise this series are designed to facilitate those processes. Each volume of this series will attempt to convey the current status of research and thought on a specific topic in development, place current research within historical perspective, and lay the intellectual groundwork for future research. These volumes are intended to provide an in-depth background on these topics for advanced undergraduates, graduate stu dents, and senior scientists. An investigator considering research in one of these areas will get an overview of the field as well as discover the status of recent research in the area.
