Schematic view of the SARS-CoV-2 genome arrangement. SARS-CoV-2 is an enveloped single-stranded positive-sense RNA beta coronavirus with a polycistronic genome ~ 30 kb in length. SARS-CoV-2 genome encodes several non-structural proteins (ORF1a and ORF1b, that are processed into NSP1-16) at the 5′-end, in addition to structural proteins (S, E, M, and N), and multiple other accessory proteins (ORF3a, 6, 7a, 7b, 8, 9b, 9c and 10) at the 3′-end
