WebSimilarly to genomic RNA, all sub-genomic transcripts have 5′-cap and 3′-poly(A)-tail. In addition, all sub-genomic SARS-CoV-2 RNAs have a common 5′-leader sequence . The presence of 5′-cap on genomic and sub-genomic SARS-CoV-2 mRNAs indicates ability of viral mRNAs to utilize a host translation machinery to synthesize viral proteins.
