The genomes and structural proteins of different human pathogenic CoVs. The polyprotein includes pp1a and pp1b. Along with the structural proteins 3′ terminus SARS-CoV- 2 genome contain accessory protein (3a, 3b,p6, 7a, 7b, 8b,9b, orf14). Similarly 3′ terminus SARS-CoV genome contain accessory protein (3a, 3b, p6, 7a, 7b, 8a,8b, 9b). Likewise 3′ terminus MERS-CoV genome contain accessory protein (3, 4a, 4b, 5, 8b) include spike (S), membrane (M), envelope (E), and nucleocapsid (N) (Walls et al., 2019; Walls et al., 2020).
