Promoter of a eukaryotic tRNAPro gene is composed of three noncontiguous regions

The 71-base-pair coding sequences of the tRNAPro gene from Caenorhabditis elegans contains all of the information required for transcription and processing in the injected oocytes. Several subclones of the DNA coding for the tRNAPro were constructed, carrying deletions or insertions, or both. Their transcriptional properties lead to the hypothesis that the tRNAPro gene promoter is composed of three discontinuous regions within the coding sequence.
