Fig. 3From: Potentially adaptive SARS-CoV-2 mutations discovered with novel spatiotemporal and explainable AI modelsSARS-CoV-2 single-nucleotide mutation spectrum. For each of the twelve classes of mutation, the number of each mutation class at single-mutation variant positions is plotted. The Wu-Hu-1 reference genome (Accession NC_045512.2) was used to define the pre-mutation nucleotide for each classBack to article page
