Norovirus from water
WebThe human norovirus genome is composed of a linear, positive-sense RNA that is ∼7.6 kb in length (14). The genome is covalently linked to the viral protein genome (VPg) at the 5′ end and polyadenylated at the 3′ end (17). There are three open reading frames (ORFs), designated ORF-1, ORF-2, and ORF-3, encoding eight viral proteins (Fig. 2). WebNational Center for Biotechnology Information
