The first two chapters of this invaluable book trace the developments of the chemistry and macromolecular structures, respectively, of proteins and nuclei acids. Similarly, the introductions to the succeeding chapters review, step by step, the historical landmarks in the topics covered. These include discoveries of biological phosphate esters, nucleotides and nucleotide coenzymes (important in intermediary metabolism), the nature of the genetic material and biological synthesis of proteins, formulation of the problem of the genetic code, and perspectives on bioenergetics. The selected papers illustrate the developments of the chemical synthesis of nucleotides and nucleotide coenzymes of ribo- and deoxy-ribo-polynucleotides (RNA, DNA), of the total synthesis of genes in the laboratory, and principles for gene amplification (PCR). Another major section covers studies of enzymes that degrade nucleic acids, the structure of transfer RNA and its role in protein synthesis, and the author's work on the elucidation of the genetic code. Finally, there are descriptions of the studies on biological membranes and the membrane protein bacteriorhodopsin, a biological proton pump. These studies elucidated the mechanism of proton translocation, which is central to bioenergetics.

This volume is comprised of 18 chapters, covering various aspects of DNA modification and RNA modified bases. It also discusses in detail circular RNA, therapeutic oligonucleotides and their different properties. The chemical nature of DNA, RNA, protein and lipids makes these macromolecules easily modifiable, but they are also susceptible to damage from both endogenous and exogenous agents. Alkylation and oxidation show a potential to disrupt the cellular redox equilibrium and cause cellular damage leading to inflammation and even chronic disease. Furthermore, DNA damage can drive mutagenesis and the resulting DNA sequence changes can induce carcinogenesis and cancer progression. Modified nucleosides can occur as a result of oxidative DNA damage and RNA turnover, and are used as markers for various diseases. To function properly some RNA needs to be chemically modified post-transcriptionally. Dysregulation of the RNA-modification pattern or of the levels of the enzymes that catalyze these modifications alters RNA functionality and can result in complex phenotypes, likely due to defects in protein translation. While modifications are best characterized in noncoding ribonucleic acids like tRNA and rRNA, coding mRNAs have also been found to contain modified nucleosides. This book is a valuable resource, not only for graduate students but also researchers in the fields of molecular medicine and molecular biology.

Guanine rich DNA has been known for decades to form unusual structures, although their biological relevance was little understood. Recent advances have demonstrated that quadruplex structures can play a role in gene expression and provide opportunities for a new class of anticancer therapeutics. A number of quadruplex-specific proteins have also been discovered. Quadruplex Nucleic Acids discusses all aspects of the fundamentals of quadruplex structures, including their structure in solution and the crystalline state, the kinetics of quadruplex folding, and the role of cations in structure and stability. The biology of quadruplexes and G-rich genomic regions and G-quartets in supramolecular chemistry and nanoscience are also considered. Surveying the current state of knowledge, and with contributions from leading experts, this is the first comprehensive review of this rapidly growing area. Quadruplex Nucleic Acids is ideal for researchers interested in areas related to chemistry, chemical biology, medicinal chemistry, molecular pharmacology, and structural and molecular biology.
