Table S1 Base percentages in the entire mitochondrial genome and in just protein-coding or RNA-coding sections. Figure S1 The pyrimidine-purine walk of each codon position of eight soluble mitochondrial-encoded protein transcripts from Arabidopsis thaliana. Figure S2 The 2-dimensional A-G and T-C walks of human mtDNA-encoded transcripts. Figure S3 Pyrimidine-purine walks of unspliced mitochondrial-encoded transcripts from Arabidopsis thaliana and Marchantia polymorpha. The introns in these transcripts do not encode known proteins.
