Those of us who read a daily newspaper or scan a weekly magazine have grown accustomed to being told that the science of genetics influences countless aspects of our existence, from human development, health, and disease to the ecological balance of our planet. We accept this, and yet most of us have only the faintest idea of what a gene really is or how it functions. This book, then, is a primer on modern genetics, and its aim is to teach any interested general reader all he or she needs to know about how genes work - and about how a detailed knowledge of their workings can be applied to some of the most pressing problems of our time. Written by two world-renowned researchers in molecular biology and illustrated with uncommon clarity and precision, Dealing with Genes will satisfy the interest of general readers, including those who have little formal background in biology. It will also serve admirably as an authoritative text for students taking nonmajors courses in biology, genetics, molecular biology, biotechnology, and related disciplines.

Many diseases are caused by a simple point mutation.

How tiny variations in our personal DNA can determine how we look, how we behave, how we get sick, and how we get well. News stories report almost daily on the remarkable progress scientists are making in unraveling the genetic basis of disease and behavior. Meanwhile, new technologies are rapidly reducing the cost of reading someone's personal DNA (all six billion letters of it). Within the next ten years, hospitals may present parents with their newborn's complete DNA code along with her footprints and APGAR score. In Genetic Twists of Fate, distinguished geneticists Stanley Fields and Mark Johnston help us make sense of the genetic revolution that is upon us. Fields and Johnston tell real life stories that hinge on the inheritance of one tiny change rather than another in an individual's DNA: a mother wrongly accused of poisoning her young son when the true killer was a genetic disorder; the screen siren who could no longer remember her lines because of Alzheimer's disease; and the president who was treated with rat poison to prevent another heart attack. In an engaging and accessible style, Fields and Johnston explain what our personal DNA code is, how a few differences in its long list of DNA letters makes each of us unique, and how that code influences our appearance, our behavior, and our risk for such common diseases as diabetes or cancer.

Program discusses the Human Genome Project, the science behind it, and the ethical, legal and social issues raised by the project.

In the fifty years since DNA was discovered, we have seen extraordinary advances. For example, genetic testing has rapidly improved the diagnosis and treatment of diseases such as Huntington's, cystic fibrosis, breast cancer, and Alzheimer's. But with this new knowledge comes difficult decisions for countless people, who wrestle with fear about whether to get tested, and if so, what to do with the results. Am I My Genes? shows how real individuals have confronted these issues in their daily lives. Robert L. Klitzman interviewed 64 people who faced Huntington's Disease, breast and ovarian cancer, or Alpha-1 antitrypsin deficiency. The book describes--often in the person's own words--how each has wrestled with the vast implications that genetics has for their lives and their families. Klitzman shows how these men and women struggle to make sense of their predicament and its causes. They confront a series of quandaries--whether to be tested; whether to disclose their genetic risks to parents, siblings, spouses, offspring, friends, doctors, insurers, employers, and schools; how to view and understand themselves and their genetics; what treatments, if any, to pursue; whether to have children, adopt, screen embryos, or abort; and whether to participate in genetic communities. In the face of these uncertainties, they have tried to understand these tests and probabilities, avoid fatalism, anxiety, despair, and discrimination, and find hope, meaning, and a sense of wholeness. Forced to wander through a wilderness of shifting sands, they chart paths that many others may eventually follow. Klitzman captures here the voices of pioneers, some of the first to encounter the personal dilemmas introduced by modern genetics. Am I My Genes? is an invaluable account of their experience, one that will become all the more common in the coming years. "An extraordinary exploration...probing the many roles and implications of genetics in our lives today.... Filled with astonishing insights, this riveting book is vital reading for us all." --Paula Zahn "Klitzman lucidly discusses the moral and psychological complexities that come in the wake of genetic testing.... An important book for anyone who has the genes for pathology, which is all of us, and I recommend it highly." --Kay Redfield Jamison, author of An Unquiet Mind "An illuminating voyage through the medical, familial and existential quandaries faced by those of us at genetic risk." --Thomas H. Murray, President and CEO, The Hastings Center
