Abstract
The 5'-terminal of Saccharomyces cerevisiae 18 S and 25 S rRNA are precisely mapped within the sequence of the rDNA repeating unit. The 3'-terminal of 25 S rRNA and 37 S pre-rRNA are located within a 548 bp segment of the rDNA repeating unit by the use of a DNA polymerase I extension technique. The analysis of the rDNA sequences at the structural gene boundaries reveals the presence of oligonucleotide repeats which may be involved in transcription or processing control mechanisms. The sequence of rDNA in the transcription termination region is determined and possible mechanisms shaping the 3'-end of 25 S rRNA are discussed.Entities:
