Fig. 3

Nucleotide compositions of human and bat coronavirus sequences. A boxplot shows the nucleotide compositions in human-CoV (alpha 229E, alpha NL63, beta HKU1 and beta OC43), bat-CoV (bat SARS, alphacoronavirus and betacoronavirus) and SARS-CoV-2 strains. Bat SARS are marked pink. A hollow arrow indicates the direction of change in oligonucleotide composition observed for SARS-CoV-2 in Figs. 1 and 2. a Mononucleotides. To compare the four mononucleotides, the scale widths on the vertical axis scale are set to the same values. b Di- and trinucleotides
