The bias of point mutations in SARS-CoV-2 variants. (A, B) The number of point mutations in SARS-CoV-2 variants. The Y axis of (A) represents the substituted base after the point mutation, and the Y axis of (B) shows the original base and substituted base at each point mutation. (C) The mutation patterns in each gene. (D) Number of point mutations in each gene divided by gene length.
