Proportion near-stop codons in human coding sequences. The proportion of triplets within a single point mutation of a stop codon, as a function of distance from the correct stop, for 500 bp upstream and 1000 bp downstream of a) all protein-coding transcripts in the human genome; b) all coding sequences in the yeast genome. Negative values represent upstream triplets and positive values downstream triplets.
