a Profile of structural elements and variants in the SARS-CoV-2 genome. The black arc lines stand for base pairs, the blue line indicates the density of base-paired nucleotides, and the red arc lines denote co-variant base pairs among different SARS-CoV-2 strains. b, c Co-variant base pairs in the 5′ UTR (b) and 3′ UTR (c), respectively. Arc lines and nucleotides colored in red indicate co-variant base pairs. EPI_ISL_402125 is the reference SARS-CoV-2 sequence.
