Reshaping Life is an authoritative yet easy-to-read description of modern molecular biology and genetics, and the ethical implications of genetic engineering. Now in its third edition, it has been fully revised and updated, taking advantage of a decade of progress in genetics and biotechnology. No other book straddles the scientific and the social dimensions of genetics as lucidly. It offers a concise working knowledge of DNA science and of those aspects of cell biology needed to understand such issues as animal cloning, genetically modified food, and gene therapy. It examines the debates on the sociological and ethical issues surrounding modern technology, laying out the issues for the reader, while urging a rational approach. Reshaping Life is well suited to general readers interested in science and medicine, as well as undergraduate and graduate students across a broad band of disciplines within the life sciences.
