Available in PDF, EPUB and Kindle. Book excerpt: Cell Growth and Cell Division is a collection of papers dealing with the biochemical and cytological aspects of cell development and changes in bacterial, plant, and animal systems. One paper discusses studies on the nuclear and cytoplasmic growth of ten different strains of the genus Blepharisma, in which different types of nutrition at high and low temperatures alter the species to the extent that they became morphologically indistinguishable. The paper describes the onset of death at high and low temperatures as being preceded by a decrease in the size of the cytoplasm and a corresponding decrease in the size of the macronucleus. The moribund organisms, still possessing structure, are motionless with no distinguishable macronuclear materials. Another paper presents the response of meiotic and mitotic cells to azaguanine, chloramphenicol, ethionine, and 5-methyltryptophan. The paper describes the failure of spindle action, arrest of second division, inhibition of cytokinesis, aberrant wall synthesis, and alterations in chromosome morphology in meiosis cells. In the case of mitosis, a single enzyme—thymidine phosphorylase—shows that reagents which inhibit protein synthesis also inhibit the appearance of that enzyme if the reagent is applied one day before it normally appears. Other papers discuss control mechanisms for chromosome reproduction in the cell cycle, as well as the force of cleavage of the dividing sea urchin egg. The collection can prove valuable for bio-chemists, cellular biologists, micro-biologists, and developmental biologists.

Download or read book Microbiology A Very Short Introduction written by Nicholas P. Money and published by OUP Oxford. This book was released on 2014-12-04 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades we have come to realize that the microbial world is hugely diverse, and can be found in the most extreme environments. Fungi, single-celled protists, bacteria, archaea, and the vast array of viruses and sub-viral particles far outnumber plants and animals. Microbes, we now know, play a critical role in ecosystems, in the chemistry of atmosphere and oceans, and within our bodies. The field of microbiology, armed with new techniques from molecular biology, is now one of the most vibrant in the life sciences. In this Very Short Introduction Nicholas P. Money explores not only the traditional methods of microscopy and laboratory culture but also the modern techniques of genetic detection and DNA sequencing, genomic analysis, and genetic manipulation. In turn he demonstrates how advances in microbiology have had a tremendous impact on the areas of medicine, agriculture, and biotechnology. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Download or read book The Biology of Amoeba written by Kwang Jeon and published by Elsevier. This book was released on 2012-12-02 with total page 655 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology of Amoeba discusses the general biology, morphology, movement and related phenomena, and biochemical and physiological studies of amoeba. This book is organized into five parts, encompassing 21 chapters that primarily focus on large free-living amoeba. After briefly discussing the highlights of studies involving amoeba, the book goes on describing the biological aspects of amoeba, including its taxonomy, phylogeny, culture, and maintaining methods. The second part describes the general morphology, ultrastructure, and cellular membrane of amoeba. The third part includes discussions on the movement of Chaos-Amoeba group; the amoeboid behavioral and motile responses; the molecular mechanism of amoeboid movement and cytoplasmic streaming; and the mechanism of endocytosis in the freshwater amoeba. Part 4 covers the effects of various groups of mutagens, antibiotics, radiation, and high pressure on phenotype change and cell activities of amoeba. The concluding part deals with the isolation and purification of amoeba's nucleic acids, as well as physical and chemical characterizations of these compounds. This part also describes the characteristics of structural features of amoeba's cell surface and the chemistry of tripartite surface. Discussions on cell cycle, nucleocytoplasmic interactions, nuclear-nuclear interactions, genetics, and strain specificity in amoeba are also covered. The book is intended as a comprehensive literature source for students in cell biology as well as for those who are using amoeba as research organisms.

Download or read book Essential Microbiology written by Stuart Hogg and published by John Wiley & Sons. This book was released on 2013-06-10 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essential Microbiology 2nd Edition is a fully revised comprehensive introductory text aimed at students taking a first course in the subject. It provides an ideal entry into the world of microorganisms, considering all aspects of their biology (structure, metabolism, genetics), and illustrates the remarkable diversity of microbial life by devoting a chapter to each of the main taxonomic groupings. The second part of the book introduces the reader to aspects of applied microbiology, exploring the involvement of microorganisms in areas as diverse as food and drink production, genetic engineering, global recycling systems and infectious disease. Essential Microbiology explains the key points of each topic but avoids overburdening the student with unnecessary detail. Now in full colour it makes extensive use of clear line diagrams to clarify sometimes difficult concepts or mechanisms. A companion web site includes further material including MCQs, enabling the student to assess their understanding of the main concepts that have been covered. This edition has been fully revised and updated to reflect the developments that have occurred in recent years and includes a completely new section devoted to medical microbiology. Students of any life science degree course will find this a concise and valuable introduction to microbiology.

Download or read book Ecology of Protozoa written by Genoveva F. Esteban and published by Springer Nature. This book was released on 2021-01-04 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book emphasises the important role that protozoa play in many natural ecosystems. To shed new light on their individual adaptive skills, the respective chapters examine the ecology and functional biology of this diverse group of eukaryotic microbes. Protozoa are well-established model organisms that exemplify many general problems in population ecology and community ecology, as well as evolutionary biology. Their particular characteristics, like large population sizes, life cycles and motile sensory behaviour, have a profound impact on their survival, distribution, and interaction with other species. Thus, readers will also be introduced to protozoan habitats in a broad range of environments. Even though this group of unicellular organisms is highly diverse, the authors focus on shared ecological patterns. Students and scientists working in the areas of eukaryotic microbiology and ecology will appreciate this updated and revised 2nd Edition as a valuable reference guide to the “lifestyles” of protozoa.

Book excerpt: From the reviews: "This is now the definitive, authoritative text on applied foraminiferal micropaleontology and should be in the library of all practicing micropaleontologists." (William A. Berggren, Woods Hole Oceanographic Institution in Micropaleontology, 47:1 (2001)"During the last 20 years there has been an explosion of publications about foraminifera from an amazing variety of disciplines: basic cell biology, algal symbiosis, biomineralization, biogeography, ecology, pollution, chemical oceanography, geochemistry, paleoceanography, and geology. This book summarizes contributions by leading researchers in these diverse fields. It is not just another text on the biology of foraminifera. Rather, Barun Sen Gupta has accomplished his objective to "write an advanced text for university students that would also serve as a reference book for professionals"." (Howard J.
