Description

Physico-chemical Properties of Nucleic Acids, Volume III revolves around three major concepts, which are intra- and intermolecular interactions, radiation effects in DNA cells, and repair mechanisms. This volume also presents the stage of specific biological functions and how repair mechanisms relate to the problem of evolution. Comprised of six chapters, this volume begins with the concept of renaturation of polynucleotides. Interactions in nucleic acids and nucleotides are discussed in several chapters. Other topics covered in this volume include polymer and salt-induced condensation of DNA and strand-breaks in the DNA of mammalian cells. The last chapter explores the stability and evolution of DNA in terms of molecular radiobiology. This chapter also presents and reviews some evolutionary problems, specifically the prebiotic evolution. The elements of stabilization and variability of genetic information are also discussed in the last chapter. As with the other volumes, this volume is a valuable reference for students and researchers in the fields of chemistry, biology, molecular biology, microbiology, and biophysics.
