Variations of mitochondrial D-loop region plus downstream gene 12S rRNA-tRNAphe and gastric carcinomas

Figure 2 Elements of transcription and translation for mitochondrial coding region 12S rRNA-tRNA^phe and non-coding D-loop region. Non-coding D-loop region and genes encoding 12S rRNA and tRNA^phe are shown with boxes on the H-strand and L-strand of mtDNA. H1 and H2 are start sites for transcription of H-strand. L is start site for transcription of L-strand. O_H is the primary origin of H-strand. mt3, mt4 and mt5 are control elements. TAS: termination-associated sequence. CSB: Conserved Sequence Block.
