Description

Nucleic Acid-Protein Recognition covers the proceedings of a symposium on ""Nucleic Acid-Protein Recognition"", held at Arden House, Harriman Campus of Columbia University on May 30-June 1, 1976. The symposium inaugurated the ""P & S Biomedical Sciences Symposia"" under the sponsorship of the College of Physicians and Surgeons of Columbia University. This book is organized into nine part encompassing 31 chapters. The opening parts describe the principles of DNA replication and the unique chromatin structure. These parts also examine the physical chemistry of the interactions of melting proteins with nucleic acids. The third part presents the different types of approaches that can be used to study the function of RNA polymerases and the development of a cell-free system that favors Pol II-catalyzed transcription from type 2 adenovirus DNA. Parts IV and V deal with the sequence determination of wild-type and mutant repressor and the restriction and modification of DNA endonucleases, while parts VI and VII focus of the recognition of tRNA. Part VIII discusses some significant studies on the assembly of ribosomes and the principles of ribosomal interactions. Lastly, Part IX considers the role of small RNA template in the reaction mechanism of RNA replicases and ribonucleases. This part also surveys the so-called RNase III cleavage of different types of RNA and the structure of nucleic acid-protein complexes.
