This book was released on 2020-10-06 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genomes of plants, animals and human consist of two components: euchromatin (representing the genes) and heterochromatin (consisting of non-coding DNAs). Unlike euchromatin, the biological role of heterochromatin is not known. To date, two types of chromosomal heterochromatin have been discovered: C- and Q-heterochromatin. C-heterochromatin is encountered in chromosomes of all higher eukaryotes, while Q-heterochromatin is present in only three higher primates: man, the chimpanzee and the gorilla. Wide variability of Q-heterochromatin has been shown to be mainly inherent in human populations. This study of Q-heterochromatin variability in natives of Eurasia and Africa highlights that interpopulation differences are related to physical environmental factors rather than to racial or ethnic features, and that the human ability to adapt to extreme conditions depends on the amount of Q-heterochromatin. The book also shows that Q-heterochromatin plays a role in the pathogenesis of certain forms of purely human pathologies such as obesity, alcoholism, addiction and atherosclerosis.

This book was released on 2013-03-09 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Critical to the accurate diagnosis of human illness is the need to distinguish clinical features that fall within the normal range from those that do not. That distinction is often challenging and not infrequently requires considerable experience at the bedside. It is not surprising that accurate cytogenetic diagnosis is also often a challenge, especially when chromosome study reveals morphologic findings that raise the question of normality. Given the realization that modern human cytogenetics is just over five decades old, it is noteworthy that thorough documentation of normal chromosome var- tion has not yet been accomplished. One key diagnostic consequence of the inability to distinguish a “normal” variation in chromosome structure from a pathologic change is a missed or inaccurate diagnosis. Clinical cytogeneticists have not, however, been idle. Rather, progressive biotechnological advances coupled with virtual completion of the human genome project have yielded increasingly better microscopic resolution of chromosome structure. Witness the progress from the early short condensed chromosomes to the later visualization of chromosomes through banding techniques, hi- resolution analysis in prophase, and more recently to analysis by fluorescent in situ hybridization (FISH).
Download or read book Human Chromosome Variation Heteromorphism and Polymorphism written by Herman E. Wyandt and published by Springer Science & Business Media. This book was released on 2011-08-20 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human Chromosome Variation: Heteromorphism and Polymorphism was formerly printed under the title “Atlas of Human Chromosome Heteromorphism”. The Atlas has become a standard reference book in most cytogenetic laboratories and is cited as a significant reference in ISCN 2009. This revised version has updated and retained the most useful pictorial sections of the first edition, including the comprehensive review of normal and “not-so-normal” variations of the human karyotype with summaries and extensive reference lists organized by chromosome number. This updated edition features concise background information on chromosome methods and applications, essential information on heteromorphism frequencies in normal and clinical populations as well as new listing and discussions of euchromatic, subtelomeric and FISH variants. The addition of two new sections make this an even more valuable reference than before. A section on common and rare fragile sites includes a short historical discussion, definitions and an extensive table of officially recognized sites that includes the HUGO name, chromosomal location, methods of induction, genes and references to the most recent molecular characterization. A new section on array CGH discusses the clinical challenge of interpreting copy number variations (CNVs) revealed by this newest technology, gives examples of various levels of interpretation and lists the several most common websites used in this interpretation.
Download or read book Human Chromosome Variation Heteromorphism Polymorphism and Pathogenesis written by Herman E. Wyandt and published by Springer. This book was released on 2017-03-28 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition now titled “Human Chromosome Variation: Heteromorphism, Polymorphism and Pathogenesis” provides the reader with an up-to-date overview of microarrays, fragile sites, copy number variations and whole genome sequencing. Greatly expanding the discussion of microarray analysis in the previous edition of the book, are new chapters on microarray and genomic analysis, plus comprehensive tables on the subtle microdeletions and microduplications that are found on each chromosome, including 235 recurring copy number variants that are associated with well-established or emerging chromosomal syndromes. The current edition features concise information on cytogenetic methods and applications, extending these discussions to DNA analysis and genome sequencing. Sections on euchromatin, heterochromatin, FISH pattern, fragile site, copy number, and DNA sequence variation are integrated with actual clinical examples from cytogenetic laboratories and from clinical practice. The principles that allow for the distinction between benign chromosome / DNA variation and pathogenic heteromorphisms / polymorphisms are discussed and include references to the latest organizational guidelines and genomic or population databases. The two previous incarnations of this book: the ‘Atlas of Human Chromosome Heteromorphism’, and ‘Human Chromosome Variation: Heteromorphism and Polymorphism’ have been standard reference works in most cytogenetic laboratories, used by laboratory directors and clinicians all around the world. While widely used sections from the previous edition on cytogenetic technologies and heteromorphisms are retained intact the present volume adds extensive material on copy number variations (polymorphisms detected by microarray analysis), fragile sites in disease and cancer, and practical views on interpreting emerging technologies, including whole exome sequencing. This book should be of interest to clinicians, technicians and students who are or will be exposed to DNA and/or chromosome analysis and the data derived from these continuously developing techniques. This fully updated book volume will bring the reader up to speed on the latest technologies, their applications, benefits and drawbacks and as such, is a must read for anyone with an interest in DNA and chromosome analysis and the distinction between benign variation and pathogenic mistakes.

Download or read book The Phylogeny of Human Chromosomes written by H.N. Seuanez and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of how man has emerged must be as old as human thought itself. However, it was not until last century that, amidst a storm of opposition and highly emotional criticism, man was first conceived as a product of evolution rather than creation. Moreover, it is not yet thirty years since the chemical composition and molecular structure of the hereditary material was fully understood or the chromosome number of man became known. It should not be surprising then, to find how little, at present, we understand how our genes and chromosomes operate, and how they have evolved during phylogeny. In this work I have discussed how our own chromosomes have been transmitted and altered as far back as we may trace their phylogeny into the past. To make the work more complete, the composition and evolution of our own genome had also to be consiered in order to understand some of the recent findings at the chromosome level. These have resulted from using methods for localizing repetitive and single copy DNA sequences in chromosomes. Moreover, the development of biochemical methods of studying evolution at the macromolecular level has not only led to a more complete understanding of the evolutionary mechanisms, but has enabled us to make comparisons with evolutionary change at the chromosome level. In addition, a simple reference to the fossil record was necessary, because impressive discoveries in recent years have supplied valuable data on man's evolution.

Download or read book Human Interphase Chromosomes written by Ivan Iourov and published by Springer Nature. This book was released on 2021-01-29 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition focuses on the study of human interphase chromosomes and its relation to health and disease. Orchestrated organization and behavior of the human genome in interphase nuclei at chromosomal level has been repeatedly shown to play a significant role in almost all basic biological processes involved in the processing and inheritance of genetic information within and between species. Accordingly, post-genomic bioscience appeals to basic and applied studies of interphase nuclei genetics and genomics with special attention to interphase chromosome behavior in health and disease. Additionally, elucidating the role of interphase chromosome behavior during development, chromosome/DNA replication, DNA reparation opens new horizons for basic and applied bioscience Studies of interphase nuclei have an appreciable impact on different areas of biomedical sciences such as cell biology, neurobiology, cancer research, developmental biology, epigenetics, cytogenetics, and medical genetics, as a whole. Moreover, development of innovative and emergent technologies to analyze interphase nuclei are closely associated with application of these techniques in diagnostic and research practices to solve reproductive problems (including infertility and spontaneous abortions), to investigate congenital malformations (including those produced by aneuploidy and other chromosome abnormalities); genetic diseases (including cardiac, immune, neurological and psychiatric diseases), and cancer. This second edition serves as a source of updated valuable information and promising ideas for a wide audience of professionals in biomedicine including researchers, scientists, and healthcare professionals in human genetics, cytogenetics, and developmental biology.

Download or read book The Barley Genome written by Nils Stein and published by Springer. This book was released on 2018-08-18 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of the state-of-the-art in barley genome analysis, covering all aspects of sequencing the genome and translating this important information into new knowledge in basic and applied crop plant biology and new tools for research and crop improvement. Unlimited access to a high-quality reference sequence is removing one of the major constraints in basic and applied research. This book summarizes the advanced knowledge of the composition of the barley genome, its genes and the much larger non-coding part of the genome, and how this information facilitates studying the specific characteristics of barley. One of the oldest domesticated crops, barley is the small grain cereal species that is best adapted to the highest altitudes and latitudes, and it exhibits the greatest tolerance to most abiotic stresses. With comprehensive access to the genome sequence, barley’s importance as a genetic model in comparative studies on crop species like wheat, rye, oats and even rice is likely to increase.
