Figure 7From: The internal initiation of translation in bovine viral diarrhea virus RNA depends on the presence of an RNA pseudoknot upstream of the initiation codonThe predicted pseudoknots of BVDV genotype 1 and 2. Stem interactions are conserved within the BVDV genotypes. Divergent nucleotides in genotype 2 pseudoknot are indicated by boxes. Note that nucleotide substitutions in one strand of stem 1 of BVDV genotype 2 are compensated by complementary mutations in the opposite strand so that stem 1 and stem 2 interactions are highly conserved.Back to article page
