Human Molecular Genetics, Third Edition has been revised and updated in the light of the discoveries following the completion of the Human Genome Project. As we enter the post genome era, the book provides a bridge between elementary textbooks and the lab research literature, so that the reader with relatively little background in the subject can appreciate and read the latest research. This new 3rd edition contains new chapters on cells and development and on functional genomics. The text has been carefully designed to engage and motivate students with clear yet detailed full color illustrations, special topic boxes (including ethical, legal and social issues) and a constant emphasis on understanding principles rather than learning detail.
