Table 2 Summary of how a DNA sequence is parsed by each of the six sonification algorithms to produce an auditory display

From: An auditory display tool for DNA sequence analysis

  1. DNA sequences are coloured red or black to signify adjacent motifs within the reading frame that is parsed by the respective algorithm. Sharps, flats and the octave (pitch) of the notes are not shown for the sake of simplicity. The ‘Di-nucleotide pairs’ algorithm produces a more complex audio display (twice the number of notes) than the ‘Di-nucleotides’ algorithm. Common notes between the two are indicated in blue. Similarly The first ATG codon of the sequence is parsed to a C note by the both the ‘Reading frame codons’ and ‘Protein sequence’ algorithms (coloured in blue). The ‘Reading frame codons’ produces two additional notes absent from the ‘Protein sequence’ algorithm prior to the sonification of the next common codon (ACG) of the first reading frame. The first TGA codon in the second reading frame and the GAC of the third reading frame are parsed to G and F notes, respectively, only by the ‘Reading frame codons’ algorithm
