Figure 2

Secondary RNA structures predicted for the 5′ (a) and 3′ (b) UTRs of HAstV-1 and design of UTR deletion mutants. The deleted nucleotides are shown in red. The green boxes indicate the start codon of ORF1a, and the orange boxes indicate the stop codon of ORF2. These structure models were generated using mfold [51] and modified using CorelDraw X6 (version 16.0.0.707). SL, stem-loop; s2m, stem-loop 2 motif.
