The Epigenetics Revolution: How Modern Biology is Rewriting Our Understanding of Genetics, Disease and Inheritance

Product Information

This had a huge effect on babies born at the time, and the effects of poor nutrition on the foetus seem to have persisted through subsequent generations. This volume explores the dimensions of epigenetics in different systems and contexts to show the central place and explanatory power of the concept for evolutionary and developmental biology. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity.

Surveying the twenty-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics. This is a much more sensible metaphor, but then on the same page she refers to "the DNA blueprint" as if she hadn't read what she had just written. DNA methylation has profound effects on how genes are expressed and ultimately on cellular, tissue and whole-body functions. This open access textbook leads the reader from basic concepts of chromatin structure and function and RNA mechanisms to the understanding of epigenetics, imprinting, regeneration and reprogramming. Epigenetic explanations arise whenever we create theoretical constructs to make sense of the complex relationships between genetic and phenotypic variation and evolution.If we drink a lot of alcohol an enzyme that metabolises it becomes more active – "upregulated" in the jargon. Nessa Carey has a PhD in virology from the University of Edinburgh and has had successful careers in both the university and commercial settings. As to why organisms evoved such complex patterns of histone modifications to regulate gene expression, the author offers an elegant explanation. Molecular genetics, developmental biology and, to a lesser degree, evolutionary developmental biology have de-emphasized the study of epigenetics.

This something-for-everyone book cohesively spans the range between professional and popular readership. McEachern and Lloyd [bh2]make the case that molecular epigenetic processes are amazingly conserved across metazoan phyla. Epigenetics is the study of emergent properties in the origin of the phenotype in development and in modification of phenotypes in evolution. The Epigenetics Revolution by Nessa Carey is a book that was recommended to me during my Biochemistry interview at Univ, so I read it over the summer after my A Levels.Nessa Carey, a molecular biologist, explains all clearly, while sucking in the uninitiated with intriguing tales of queen bees, tortoiseshell cats, un-identical identical twins and lots more. In this book, Nessa Carey describes how the world around you can and will influence everything about the way your body works by changing your genetic material. The author's writing is clear, substantive, vivid, acutely insightful in matters relating to evolution, witty while her frequent use of analogy exemplary. A hugely compelling explanation of the very latest from the frontline of modern biology … The Epigenetics Revolution traces the thrilling path this discipline has taken over the last twenty years. So for five years I worked at the Metropolitan Police Forensic Science Lab in London and studied part-time.

The first chapter, by Schurmans takes a molecular perspective on epigenetics and deals with the role of chromatin modification in neural development. As an introduction to this emerging field, The Epigenetics Revolution by Nessa Carey is a must-read for every intelligent person who likes to know what is going on in modern science. In the factory, molten metal or plastic gets poured into the mould thousands of times and, unless something goes wrong in the process, out pop thousands of identical car parts. She reveres the philosophies of science, in particular the principle of hypothesis and test, the crucial importance of a well-chosen experimental system, and the power of incisive thought.

Since all phenotypic variation has a physical basis, we can define epigenetics at the molecular level as the set of modifications to our genetic material that change the ways of gene expression - switch on, switch off, or some intermediate stage - but which does not alter our genome which we can transmit in all its purity to our descendants. Concepts such as epigenetics are required, not because biological systems are fundamentally indeterminate but because their complexity prohibits the construction of an exhaustive deterministic framework. That said, there was much I did enjoy, especially her ability to switch between the nitty gritty account of lab work and a more abstract analysis of the scientific method.

She hasn't, though, solved the problem of how to make the mind-numbing complexity of some genomic interactions and the confusing nomenclature of genes palatable to the general reader. Often such children who suffered from abuse or neglect in their early years have substantially higher risk as adults of mental health problems than the general population.Surprisingly, there is no mention of the early work by nobel laureates Barbara McClintock or Paul Berg. This didn't last because I was allergic to fur, unable to think in 3D (not good for anatomy), quite bored and really rubbish at the course. To appreciate the detail into which Carey goes to describe these molecular events, you'll probably need to be either one of those scientists or studying to become one.
