title: [Processing of tRNA].
abstract: The article reviews various aspects of tRNA biosynthesis in pro- and eukaryotes. Some data on the tRNA gene localization are presented. Structures of tRNA precursors are given; their conversion into mature tRNA molecules and the corresponding enzymatic systems are discussed in detail. Special emphasis is given to the transcription of tRNA genes and processing of tRNA precursors in vitro. Similarities and diversities of tRNA processing in pro- and eukaryotes are discussed.
