Figure 2. The three genomic RNA segments (L, M, and S) of an Andes virus and their encoding proteins. Their sequence accession numbers in GenBank are NC003468, NC003467, and NC003466.38 Brown lines represent the 5′-methylated cap and some nucleotides transferred from host cell mRNAs to the viral mRNAs. ORF: open reading frame. UTR: untranslated region.
