    Abstract: The policy adopted in Volume 1 of this series of including a relatively small number of topics for detailed review has been continued here. The techniques selected have received considerable attention in recent years. F or this reason and because of the significance of the characterisation data, further coverage of 13C nuclear magnetic resonance spectroscopy and small angle neutron scattering is given in the first two chapters. In Chapter I a large part of the review describes the determination of monomer sequence distributions and configurational sequences in copolymers formed from more than one polymerisable monomer. The review on neutron scattering (Chapter 2) is directed towards the determination of the chain conformation in semi-crystaIIine polymers, which has provided important results for the interpretation of chain folding and morphology in crystaIIisable polymers. Laser Raman spectroscopy has also been used for morphological studies, and this application together with a description of the theoretical and experimental aspects of the technique is given in Chapter 3. X-ray photoelectron spectroscopy because of its extreme sensitivity to surface characteristics has provided information on polymeric solids that could not be obtained by other techniques. The principles and practice of this ESCA technique, including its use for simple elemental analysis, structural elucidation and depth profiling, are described in Chapter 4. The final two chapters are mainly concerned with the chain conformation of polymers in dilute solution. Ultrasonic techniques (Chapter 5) show pmmise for observing the dynamics of conformational changes.

    Abstract: 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 from the application of recombinant DNA technology to all manner of problems. I have added a sixth chapter indicating the impact of this work on our concepts of gene structure. I should like to thank Ed Byard, Bill Evans, Charles Schorn and Ed Ward, colleagues in the Biology Department at the University of Winnipeg, and Andrew Spence, a student in the department, for their comments on the manuscript of the second edition, and to reiterate my thanks to all those in the Department of Genetics at the University of Sheffield who commented on the first edition.

    Abstract: The emergence of Mossbauer spectroscopy as an important experi­ mental technique for the study of solids has resulted in a wide range of applications in chemistry, physics, metallurgy and biophysics. This book is intended to summarize the elementary principles of the technique at a level appropriate to the advanced student or experienced chemist requiring a moderately comprehensive but basically non-mathematical introduction. Thus the major part of the book is concerned with the practical applications of Mossbauer spectroscopy, using carefully selected examples to illustrate the concepts. The references cited and the bibliography are intended to provide a bridge to the main literature for those who subseouent­ ly require a deeper knowledge. The text is complementary to the longer research monograph, 'Mossbauer Spectroscopy', which was written a few years ago in co-authorship with Professor N.N. Greenwood, and to whom I am deeply indebted for reading the preliminary draft of the present volume. I also wish to thank my many colleagues over the past ten years, and in particular Dr. R. Greatrex, for the many stimu­ lating discussions which we have had together. However my greatest debt is to my wife, who not only had to tolerate my eccen­ tricities during the gestation period, but being a chemist herself was also able to provide much useful criticism of the penultima te draft.

    Abstract: 1 Introduction -- 2 Structural aspects of isoenzymes -- 3 Isoenzymes in genetics and evolution -- 4 Isoenzymes in development and differentiation -- 5 Isoenzymes in metabolic regulation -- 6 Isoenzymes in cancer -- 7 Isoenzymes in diagnosis and disease -- 8 Separation and determination of isoenzymes.
    Abstract: Isoenzymes were 'discovered' 20 years ago and were at first regarded as interesting but rare occurrences. Since then a wealth of information on enzyme heterogeneity has accrued and it now seems likely that at least half of all enzymes exist as isoenzymes. This is important in many areas of biological and medical science. Thus isoenzyme studies have provided the main experimental substance for the neutral drift controversy in genetics and evolution; they have greatly extended our understanding of metabolic regulation not only in animals but also in bacteria and plants; their existence has made available a multitude of highly sensitive markers for the study of differentiation and development, as well as providing indices of aberrant gene expression in carcinogenesis and other pathological processes. Iso­ enzymes are also being used increasingly in diagnostic clinical bio­ chemistry. It is surprising that this phenomenon which affects such a high pro­ portion of enzymes and is clearly important in biochemistry should receive such scant attention in the standard textbooks of that subject, the formal treatment of isoenzymology in these rarely exceeding one or two pages. This may be because the 'pure biochemist' has tended to regard variation in enzyme properties between tissues more as an unwanted complication than as a potential source of insight into diversity of biological function.
