FIGURE 1: Nucleotide sequence of suppressed and non-suppressed frameshift mutations in the RNA-maturase coding part of the second intron of the cytochrome b gene.

Note that both mutations create double ochre stop codons, one immediately after the addition of adenine (M3041) and the other after a shift of nine amino acids after the addition of adenine (G5006). Numbering like in table 1.
