Book Description
Integrating classical knowledge of chromosome organisation with recent molecular and functional findings, this book presents an up-to-date view of chromosome organisation and function for advanced undergraduate students studying genetics. The organisation and behaviour of chromosomes is central to genetics and the equal segregation of genes and chromosomes into daughter cells at cell division is vital. This text aims to provide a clear and straightforward explanation of these complex processes. Following a brief historical introduction, the text covers the topics of cell cycle dynamics and DNA replication; mitosis and meiosis; the organisation of DNA into chromatin; the arrangement of chromosomes in interphase; euchromatin and heterochromatin; nucleolus organisers; centromeres and telomeres; lampbrush and polytene chromosomes; chromosomes and evolution; chromosomes and disease, and artificial chromosomes. Topics are illustrated with examples from a wide variety of organisms, including fungi, plants, invertebrates and vertebrates. This book will be valuable resource for plant, animal and human geneticists and cell biologists. Originally a zoologist, Adrian Sumner has spent over 25 years studying human and other mammalian chromosomes with the Medical Research Council (UK). One of the pioneers of chromosome banding, he has used electron microscopy and immunofluorescence to study chromosome organisation and function, and latterly has studied factors involved in chromosome separation at mitosis. Adrian is an Associate Editor of the journal Chromosome Research, acts as a consultant biologist and is also Chair of the Committee of the International Chromosome Conferences. The most up-to-date overview of chromosomes in all their forms. Introduces cutting-edge topics such as artificial chromosomes and studies of telomere biology. Describes the methods used to study chromosomes. The perfect complement to Turner.

Book Description
Molecular Structure of Human Chromosomes is an authoritative guide to genetics, focusing on human genome. This reference compiles contributions covering available knowledge on human genome structure and organization, which the previous researches fail to encompass. This text provides a comprehensive discussion of cytogenetic techniques, emphasizing their application to human genome studies and examinations. The book is divided into nine chapters. It explains the molecular organization and function of the human genome and the DNA sequences in man. It also discusses the localization of human gene by in situ hybridization and the approaches to gene mapping. The book describes the structure of the chromosomes and the trends in chromosome techniques; banding and polymorphism; and repetitive DNA and primate evolution. Various practitioners in genetics and biology will find this book a good reference. Students and novices in these fields will also find this book an excellent guide.

Praise Of Chromosome "Folly": Confessions Of An Untamed Molecular Structure

Book Description
When examined carefully at the molecular level, the chromosome turns out to have created its own private world full of tricks, back door exits and novel solutions. This “folly” makes it an untamed innovator. Geneticists have been bewildered for decades. What kind of creature was actually the chromosome? Was it plastic, changing by innumerous rearrangements and mutations all the time; or was it a rigid structure which has preserved its basic organisation and functions since the dawn of the cell? It is this conflicting state that seems to be at the base of its “folly”. Perplexed by this behavior, cell biologists have called it a junkyard and even the ultimate parasite. Moreover, the chromosome has been regarded as a passive cell organelle prone to random mutations and subjected to the mercy of selection.The latest molecular information discloses a radically different picture in which the chromosome appears as an independent molecular structure that follows its own path. It does not obey gravity, randomness, selection or magnetism.By anchoring the chromosome's contradictory behavior on molecular processes directed by atomic self-assembly, Lima-de-Faria expands a novel view of the chromosome with unexpected implications for genetics, evolution and physics.This timely book contains the latest information on the molecular organization of the chromosome. The information is original and is presented in an unorthodox way, while carefully chosen elucidating and attractive figures serve to add clarity to the subject treated. Thus, the book will add greatly to the general debate on the evolution of living organisms, and will be of particular interest to those in the biotechnological field.

Book Description
This volume in the Monographs in Evolutionary Biology series addresses issues that are part of an emerging area of research loosely called "mo lecular evolution. " Its practitioners include both molecular biologists cu rious about the evolutionary implications of their data and evolutionary biologists pushing their analyses to the molecular level. The union of these fields of molecular and organismal biology has been turbulent at times, and, as shall be seen, this dialectic has led to some very serious challenges to long-held notions about the role of natural selection in evolution and the economy of genome organization in eukaryotes. As an inevitable outgrowth of molecular biology, molecular evolution is necessarily a young discipline, but it can already point proudly to two major discoveries. The first, is the molecular clock, a concept that has emerged from the analysis of at least four data sets-amino acid sequences, immunologic data, DNA renaturation studies, and, recently, analyses of DNA sequences. The reality of a strong stochastic component in the evolution of nucleotide sequences can no longer be doubted, although the accuracy of the clock with regard to particular sequences and within particular groups of or ganisms should be independently measured each time it is used. Never theless, molecular clocks will assume increasingly important roles in phy logenetic reconstructions, especially since the fossil record is so fragmentary. The second major discovery of molecular evolution has been the incredible complexity of the eukaryotic genome.

Book Description
The study of evolution at the molecular level has given the subject of evolutionary biology a new significance. Phylogenetic 'trees' of gene sequences are a powerful tool for recovering evolutionary relationships among species, and can be used to answer a broad range of evolutionary and ecological questions. They are also beginning to permeate the medical sciences. In this book, the authors approach the study of molecular evolution with the phylogenetic tree as a central metaphor. This will equip students and professionals with the ability to see both the evolutionary relevance of molecular data, and the significance evolutionary theory has for molecular studies. The book is accessible yet sufficiently detailed and explicit so that the student can learn the mechanics of the procedures discussed. The book is intended for senior undergraduate and graduate students taking courses in molecular evolution/phylogenetic reconstruction. It will also be a useful supplement for students taking wider courses in evolution, as well as a valuable resource for professionals. First student textbook of phylogenetic reconstruction which uses the tree as a central metaphor of evolution. Chapter summaries and annotated suggestions for further reading. Worked examples facilitate understanding of some of the more complex issues. Emphasis on clarity and accessibility.
