The mitochondrial genome of bakers’ yeast, Saccharomyces cerevisiae, contains genes for 25 tRNAs, two rRNAs, an RNA species involved in tRNA processing, and structural genes for three subunits of cytochrome c oxidase, three subunits of the ATPase, the apoprotein of cytochrome b, and a ribosomal protein (reviewed in Ref. 12). So far, eight sites of transcription initiation have been identified (9); while some additional promoters may remain to be defined, it is clear that groups of adjacent genes are usually transcribed together (e.g., Ref. 16, 25, and 43). Thus, RNA processing events play an important, if not essential, role in mitochondrial gene expression.
