Transcriptional mapping of the rat liver mitochondrial genome

We have identified and mapped nine discrete poly(A)-containing RNAs (RNA-2 to RNA-10) transcribed from rat liver mitochondrial DNA. The 5'-terminal fragments have been sequenced in five of these. The transcriptional map of rat mitochondrial DNA is homologous to those for mitochondrial DNAs of man and mice. The 5'-terminal nucleotide sequences of poly(A)-containing RNAs from rat liver mitochondria are similar in structure to those of HeLa cells studied by other authors; none of them have leader sequences.
