Molecular Associations in Biology provides information pertinent to molecular biology. This book discusses several topics, including DNA replication, calculation of intermolecular energies, and thermodynamic parameters of polynucleotides. Organized into 35 chapters, this book starts with an overview of the specific association of the purine and pyrimidine bases in the nucleic acids, which provides the basis for storage, expression, and transmission of genetic information. This text then explores the secondary structures, interactions, and replication processes of nucleic acids. Other chapters consider the complex biological process of protein synthesis. This book discusses as well the methods of photodynamic action, which is significant in detecting energy transfer from dye to the biomolecule and identifying the free radicals produced. The final chapter deals with the macroscopic properties of molecular systems, which refer to such concepts as volume, mass, pressure, temperature, and pH. This book is a valuable resource for biophysicists, organic chemists, biochemists, and biologists.
