Figure 5From: Mitochondrial-encoded membrane protein transcripts are pyrimidine-rich while soluble protein transcripts and ribosomal RNA are purine-richPyrimidine-purine codon position walks of select mitochondrial-encoded transcripts. (A) Membrane protein transcript, human COX1 (C) Soluble protein transcript, Chondrus crispus ribosomal protein S12. For each codon position step, the x-axis was incremented by 3 for comparison to the complete transcript. A pyrimidine-purine walk of (B) human 16S ribosomal RNA is also shown for comparison.Back to article page
