The book, written by American scientists who have received recognition as talented university-level teachers, examines modern concepts of biochemistry in accordance with the changed ideology of this science. Volume 3 includes Part III "Ways of information transmission", answers to questions, problem solving and subject-name index on the material of volumes 1-3, as well as the accepted abbreviations and vocabulary of terms. The main dogma of molecular biology and its modern understanding are discussed , processes of transmission and storage of genetic information as in bacteria , and eukaryotes (replication,) transcription, broadcast, Reparation and Recombination , Structure of chromosomes, mechanisms of enzymatic processes , functions of different RNAs in the cell, ribozyme, splicing, Alternative splicing, processing. Detailed description of protein biosynthesis, its transport to the site of use and further destruction, regulation of gene expression Each chapter (as in Volumes 1 and 2) provides examples from medicine, molecular biology, and related fields, as well as interesting assignments and questions.
