Implantation of Ova

the many and different endeavors which aim at an explanation of living phenomena in terms of molecules and their properties. The present work by 25 outstanding scientists in molecular biology points up the tremendous upsurge of research activity on the molecular level. The book contains 20 examples of this research, all written by investigators deeply engaged in it. The chapters illustrate the diversity of the problems facing research workers and the methods for elucidating them. Of particular interest were the chapters by Kurt Felix, principles of molecular biology; Isidore Gersh, cytochemical studies with the electron microscope; Richard L. Sinsheimer, current ideas of the structure of desoxyribonucleic acid (DNA); Arthur Kornberg, enzymatic synthesis of DNA; Alexander Rich, bearing of structural studies on relationships of DNA and RNA; Christian B. Anfinsen, protein structure and biological activity; Arthur L. Lehninger, on oxidation, phosphorvlation, active transport, and mitochondria structure; Jui H. Wang, enzyme models; Julian M. Tobias and Phillip G. Nelson, structure and function in nerve, and R. E. Zirkle, structure of the mitotic spindle. This work is a scientific tour de force. It is uniformly edited and impeccably published under the auspices of a scholarly publisher This book is recommended without reservation. It will enjoy a long success in the hands of scholars concerned with the dynamics of molecular biology.
