FIGURE 1.
5′ RNA editing is predicted for two of the five tRNAs encoded in the mitochondrial genome of Physarum polycephalum. (A) Mitochondrial tRNAmet1 and tRNAmet2 each contain a mismatch at the beginning of the acceptor stem (Antes et al. 1998). Sites predicted to contain a G residue in the mature tRNA products are indicated with arrows; sites of internal C insertions identified by Antes et al. (1998) are indicated with arrowheads. (B) Apparent overlap of the 5′ end of tRNAmet2 with the 3′ end of ppoRNA. The approximate positions of primers used for reverse transcription (gray) and PCR (black) of nascent transcripts are shown.
