By two-dimensional polyacrylamide gel electrophoresis, yeast mitochondrial tRNA is fractionated into 27 major species. All but 6 of them migrate distinctly from cytoplasmic tRNAs. Migration of mitochondrial DNA-coded mitochondrial tRNAs shows the occurence of only one cytoplasmic tRNA in mitochondria. Several mitochondrial tRNA spots are identified on the electrophoregrams, some of them show isoaccepting species (Val, Ser, Met, Leu). It is suggested that there are sufficient mitochondrial tRNA genes on yeast mitochondrial DNA to allow mitochondrial protein biosynthesis by the mitochondrial tRNAs alone. Guanosine + Cytidine content and rate base composition are reported for some individual species. Mitochondrial tRNAPhe lacks Ribothymidine.

The sequence of a 6.24 kb DNA segment of the mitochondrial genome from rat liver has been determined. It comprises several genes coding for mitochondrial protein subunits and five tRNA genes in the following order: cytochrome oxidase subunit I - tRNA (UCN) (Ser) -tRNA(Asp) - cytochrome oxidase subunit II - tRNALys -ATPase subunit - cytochrome oxidase subunit III -tRNA(Gly) - potential open reading frame - tRNA(Arg) -two potential open reading frames. The tRNA genes were detected by a computer search programme. The assignments for the protein coding sequences were made through comparison with known sequences, mainly from the yeast mitochondrial proteins (e.g. Bonitz et al. 1980). Our data are discussed with regard to the features of gene arrangement, codon usage, and tRNA structure in mammalian mitochondria (Anderson et al. 1981).
