Virion and genomic structure of SARS-CoV-2. (A) Schematic structure of the SARS-CoV-2 virion, (B) structural organization of the SARS-CoV-2 genome. Structural proteins, Spike (S), envelope (E), membrane (M) and nucleocapsid (N) proteins, non-structural proteins translated from ORF 1a and ORF 1b and accessory proteins, including 3a, 3b, 6, 7a, 7b, 8a, 8b, and 9b (for SARS-CoV), and 3a, 6, 7a, 7b, 8, and 10 (for SARS-CoV-2) are indicated. SARS-CoV-2, severe acute respiratory syndrome coronavirus 2; ORF, open reading frame.
