[Characteristics of the organization and expression of individual genes in eukaryotic cells].

The modern views on the organization and expression of single genes in eukaryotic cells, RNA structure and biosynthesis are reviewed. The problems of unstable gene localization ("mobile dispersed genetic elements") of some structural genes of cellular and viral origin are discussed. Peculiarities of transcription and processing of mRNA, pre-mRNA splicing are described. The information on the mechanisms of pre-mRNA splicing in normal and virus-infected eukaryotic cells, the role of low molecular nuclear RNA in the RNA splicing as signals for less than recognition greater than by specific nucleases and RNA synthetases are also regarded.
