Book Synopsis Ultrastructure, Macromolecules, and Evolution by : Lawrence S. Dillon
Download or read book Ultrastructure, Macromolecules, and Evolution written by Lawrence S. Dillon and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thus far in the history of biology, two, and only two, fundamental principles have come to light that pervade and unify the entire science-the cell theory and the concept of evolution. While it is true that recently opened fields of inves tigation have given rise to several generalizations of wide impact, such as the universality of DNA and the energetic dynamics of ecology, closer inspection reveals them to be part and parcel of either of the first two mentioned. Because in the final analysis energy can act upon an organism solely at the cellular level, its effects may be perceived basically to represent one facet of cell me tabolism. Similarly, because the DNA theory centers upon the means by which cells build proteins and reproduce themselves, it too proves to be only one more, even though an exciting, aspect of the cell theory. In fact, if the matter is given closer scrutiny, evolution itself can be viewed as being a fundamental portion of the cell concept, for its effects arise only as a consequence of changes in the cell's genetic apparatus accumulating over geological time. Or, if one wishes, the diametrically opposite standpoint may be taken. For, if current concepts of the origin of life hold any validity, the evolution of precellular organisms from the primordial biochemicals must have proceeded over many eons of time prior to the advent of even the most primitive cell.

Book Synopsis The Inconstant Gene by : Lawrence Dillon
Download or read book The Inconstant Gene written by Lawrence Dillon and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why should the gene be suggested to be inconstant when the contrary view, that gene structure is invariant except through mutagenic processes induced by potent external factors, has long been a universal doctrine of genetics? Indeed, during the early part of the present century before mutation was recognized as being of general occurrence, the seeming unvarying nature of the gene led to skepticism regarding the validity of the evolutionary theory; only later could the origins of the morphological differences between individuals and species be attributed to a combination of mutation and evolution, involving natural forces selecting between favorable and unfavorable genetic changes. But during the past several decades, as knowledge of the macromolecular constitution of or ganisms has increased to the point where even the primary structures of the genes themselves are being revealed on a routine basis, it has become increas ingly difficult to ascribe all the resulting observations to ordinary mutagenesis and natural selection. Some more profound mechanism often seems to be present that influences both the constancy and inconstancy of the genes, an ap paratus whose existence this study hopes to reveal. In seeking to demonstrate the universality of this mechanism, data are sought through the numerous activities of organisms of many types wherever gene action changes are manifest.

Book Synopsis Evolutionary Pathways and Enigmatic Algae by : Joseph Seckbach
Download or read book Evolutionary Pathways and Enigmatic Algae written by Joseph Seckbach and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time a book is available devoted to cellular evolution and to the biology of Cyanidium and other enigmatic cells. Twenty international experts present their views and reviews, postulating new theories on compartmental (direct filiation) eukaryogenesis, discussing the endosymbiotic hypothesis, and providing conceptions on molecular RNA and protein sequences of genes for phylogenetic applications. The book contains exclusive reports on additional species (newly discovered) of the Cyanidium group. Special attention is given to the red algae and other enigmatic/unicellular algae including Nanochlorum eucaryotum (a green alga with minimal eukaryotic characteristics). The mystifying taxon of Glaucocystophyta (containing Cyanophora paradoxa -- the endosymbiotic `guinea pig' with cyanelles/host special relationships) is examined. For biologists, post/graduate students in biology, and anyone seriously interested in algae, evolution, cytology, biochemistry and questions of nucleated cell differentiation or cellular endosymbiosis.

Book Synopsis Current Mammalogy by : H.H. Genoways
Download or read book Current Mammalogy written by H.H. Genoways and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: When I first proposed a series entitled Current Mammalogy to the pub lishers, they were reluctant to undertake such a project because they viewed the field of mammology as overly fragmented. At first I found this idea to be difficult to accept; however, upon reflection, I came near to agreeing with it. Although many of us work on mammals, we gen erally feel more allegiance to our specialties, such as systematics, ge netics, cytogenetics, ecology, behavior, pest control, paleontology, wildlife management, primatology, and marine mammalogy, than we do to the general field of mammalogy. However, rather than becoming discour aged from pursuing this project, I became more certain than ever that a series such as Current Mammalogy was needed. We hope to make this series a place where specialists can present their ideas not only to other members of their specialty, but to those outside the area as well. Hopefully, this exchange of ideas will be a mutually beneficial exercise. The Editorial Board of Current Mammalogy has decided to keep the range of subjects in each volume as broad as possible rather than concentrating on one or two topics, in the hope that this will keep the series as useful as possible to the broadest range of readers.

Available in PDF, EPUB and Kindle. Book excerpt: Plasmodesmata are minuscule plasma corridors between plant cells which are of paramount importance for transport, communication and signalling between cells. These nano-channels are responsible for the integrated action of cells within tissues and for the subdivision of the plant body into working symplast units. This book updates the wealth of new information in this rapidly expanding field. Reputed workers in the field discuss major techniques in plasmodesmatal research and describe recent discoveries on the ultrastructure, the functioning and the role of plasmodesmata in intracellular transport and communication, in cell differentiation, plant development and virus translocation.
Book Synopsis Concepts in Cell Biology - History and Evolution by : Vaidurya Pratap Sahi
Download or read book Concepts in Cell Biology - History and Evolution written by Vaidurya Pratap Sahi and published by Springer. This book was released on 2018-03-01 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses central concepts and theories in cell biology from the ancient past to the 21st century, based on the premise that understanding the works of scientists like Hooke, Hofmeister, Caspary, Strasburger, Sachs, Schleiden, Schwann, Mendel, Nemec, McClintock, etc. in the context of the latest advances in plant cell biology will help provide valuable new insights. Plants have been an object of study since the roots of the Greek, Chinese and Indian cultures. Since the term “cell” was first coined by Robert Hooke, 350 years ago in Micrographia, the study of plant cell biology has moved ahead at a tremendous pace. The field of cell biology owes its genesis to physics, which through microscopy has been a vital source for piquing scientists’ interest in the biology of the cell. Today, with the technical advances we have made in the field of optics, it is even possible to observe life on a nanoscale. From Hooke’s observations of cells and his inadvertent discovery of the cell wall, we have since moved forward to engineering plants with modified cell walls. Studies on the chloroplast have also gone from Julius von Sachs’ experiments with chloroplast, to using chloroplast engineering to deliver higher crop yields. Similarly, advances in fluorescent microscopy have made it far easier to observe organelles like chloroplast (once studied by Sachs) or actin (observed by Bohumil Nemec). If physics in the form of cell biology has been responsible for one half of this historical development, biochemistry has surely been the other.
