My aim in writing Gene Function has been to present an up-to-date picture ofthe molecular biology of Escherichia coli. I have not attempted a chronological description, believing that a mechanistic account is more useful for such a highly developed field. I have divided the book into four parts. Part I is a general introduction to bacterial systems, their genetic material, structure, composition and growth. It has seemed desirable to include herein a brief preview of the remaining text, to...

The last few years have seen the rapid development of new methodology in the field of molecular biology. New techniques have been regularly intro duced and the sensitivity of older techniques greatly improved upon. Developments in the field of genetic engineering in particular have con tributed a wide range of new techniques. In Volume 1, published in 1983, we introduced the reader to a selection of the more advanced analytical and preparative techniques which we considered to be frequentl...

Writing this second edition of Biochemical Genetics proved to be more difficult than I had anticipated. The fixed format of the series meant that the addition of new material was made possible only by the dele tion of old. Since the book is intended for a student audience, I have retained the historical approach of the first edition and added new material only when it demonstrates a principle more effectively. At the time of writing, we are witnessing an information explosion resulting fro...

I wrote this book because I believe that the welfare of animals is a very important subject but one about which there is a of confusion and muddled thinking. I wanted to great deal write a book which straightened out some of the confusion by looking in detail at one particular problem: how to recognize animal suffering. The book is written for anyone interested in animals and the controversies over how human beings should treat them. I have tried to convince people who might otherwise feel...

Mammalian hibernation is commonly thought of as something completely out of the ordinary, a "unique and unorthodox state." The present book takes the opposite view. It argues that the physiological achievements of hibernators do not deEend on special mechanisms but on special use of ordinary mechanisms. It is precisely this that makes the hibernators important. If the hibernators de pend on some unique physiological principle their study is that of a biological curio. But if they are using...
