Schematic representation of SARS-CoV-2 structure. The single-stranded RNA viral genomic assembly of 29,674 nucleotide base pair encodes open reading frame 1a, open reading frame 1b, Spike glycoprotein, Envelope, Membrane, and Nucleocapsid proteins. ORF1a gene encodes papain-like protease and 3CL protease, ORF1b gene encodes an RNA-dependent RNA polymerase, a helicase, and an endoribonuclease
