RNA-DNA differences in human mitochondria restore ancestral form of 16S ribosomal RNA.

Abstract excerpt

RNA transcripts are generally identical to the underlying DNA sequences. Nevertheless, RNA-DNA differences (RDDs) were found in the nuclear human genome and in plants and animals but not in human mitochondria. Here, by deep sequencing of human mitochondrial DNA (mtDNA) and RNA, we identified three RDD sites at mtDNA positions 295 (C-to-U), 13710 (A-to-U, A-to-G), and 2617 (A-to-U, A-to-G). Position 2617, within...
