What Is The Function Of A Nucleic Acid

RNA Structure and Function

This book focuses on the current status of our understanding of RNA, a key biological molecule. The various RNAs covered are messenger RNA, ribosomal RNA, transfer RNA, noncoding RNAs, modified nucleosides, and RNA enzymes. The different chapters detail methods to investigate RNA structure and function, the chemistry of modified RNAs, and the latest advances in our understanding of the vast array of biological processes in which RNA is involved. RNA, in one form or another, touches almost everything in a cell. RNA has both structural and catalytic properties. RNA fulfills a broad range of functions. These molecules are no longer seen as passive elements transferring the genetic information from DNA into proteins but regulate the activity of genes during development, cellular differentiation, and changing environments. RNAs are involved in various aspects of cell physiology and disease development. Discoveries of RNA with unexpected diverse functions in healthy and diseased cells, such as the role of RNA as both the source and countermeasure to cancer or severe viral infection, stimulate new trends, passion, and solutions for molecular medicine. In this book, fundamental questions about the biochemical and genetic importance of RNA, how mRNAs are generated and used to produce proteins, how noncoding and catalytic RNAs mediate key cellular processes, how to determine RNA structure and how to apply RNA in treatment of diseases. This book is an essential resource for researches in academia and industry contributing to the development of new RNA therapeutics. The book is geared toward scientists from the graduate level on up and particularly appeals to active investigators in RNA biology, molecular biology, and biochemistry.

The Nucleic Acids

The Nucleic Acids, Volume III covers the significant progress in understanding the chemistry and biological importance of the nucleic acids. This volume is composed of 12 chapters, and begins with an overview of the general principles of the determination of weight, shape, and dimension of large molecules in solution. These topics are followed by discussions on the photochemistry of nucleic acids and its constituents; chemical and enzymic synthesis of polynucleotides; and nucleic acid content and dynamics of bacterial viruses. The next chapters describe the biosynthesis of purine and pyrimidine nucleotides. A chapter examines the relationship of nucleic acid and protein synthesis through considering cell-free systems, particularly those derived from mammalian tissues. Another chapter looks into the protein biosynthesis in intact bacterial cells. The final chapters explore the nucleic acid metabolism, with a special emphasis on the effect of radiation on the process. This book is of value to organic chemists and biochemists.
