Table 2 Description of the navigation buttons from where users can begin playing the audio and visual displays

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

Button set 1 RNA features associated with coding regions
5′UTR 5′ untranslated region
Poly-/-protein Two buttons representing the coding region before and after the -1 frameshift position of the large polyprotein
9 U regions Each navigates to an untranslated region between ORF’s
-S- Region coding for the canonical S protein
-E- Region coding for the canonical E protein
-M- Region coding for the canonical M protein
-N- Region coding for the canonical N protein
ORF 3a, ORF 6, ORF 7a, ORF 7b, ORF 8, ORF 10 Regions thought to code for other proteins or polypeptides
3′UTR 5′ untranslated region
Button set 2 RNA features associated with the NSP proteins
5′UTR 5′ untranslated region
N1—N16 Location of the 16 NSP proteins within the large polyprotein
14 C sites Cleavage sites within the translated polyprotein giving rise to the 16 individual NSP proteins
S—ORF 10 Region of the RNA sequence downstream of the polyprotein
3′UTR 5′ untranslated region
Button set 3 RNA features associated with the TRS regions
5′UTR 5′ untranslated region
T1—T10 Location of TRS 1 to TRS 10. TRS1 is sometimes referred to as the leader TRS and is linked to the subsequence TRS 2—10 to produce the sub-genomic regions during transcription
5 SL regions Stem Loop regions giving rise to structured regions of RNA. These are formed due to sequence complementarity and base pairing
12 Seq regions Undefined sequences between the TRS regions, these often correspond closely to the ORF regions
3′UTR 5′ untranslated region
