Table 1 The mapping of each RNA feature into a layer of the auditory display

From: Real-time audio and visual display of the Coronavirus genome

Description RNA feature Note range When is the feature sonified
As the sequence is processed each is sonified to create a constant audio stream Nucleotide 4 Throughout the genome
Di-nucleotide 16 Throughout the genome
GC Content (10 bp) 10 Throughout the genome
GC Content (100 bp) 10 Throughout the genome
Three of the same nucleotide repeats Example: the poly-A tail 4 Anytime when condition is true
Codons (translation only) Codon Frame 1 20 Between start and stop codons
Codon Frame 2 20 Between start and stop codons
Codon Frame 3 20 Between start and stop codons
Trinucleotides (transcription only) Only the 1st and 3rd nucleotides are considered 16 Throughout the genome
Untranslated regions Intragenic UTR regions (excluding 5′ and 3′ UTRs) 16 At genomic regions defined by GenBank metadata [2]
Individual nucleotides were mapped to higher octaves ranges for the sake of audio clarity
Transcription regulating sequences (TRS) Each nucleotide in TRS1 through to TRS10 16
Polyprotein cleavage sites (translation only) Nucleotides that code for the cleaved AA residues 4
Stem and Loop regions (SL) Each nucleotide in the identified region 16
