(a) Comparison of complexes between Benzo(a)pyrene and RNA. (A) Complex with a stem loop of human histone mRNA (PDB 1KK); (B) complex with stem loop I of S. cerevisiae stem loop I of U2 snRNA (PDB 2O33). Each nucleotide is identified by a different color: A = yellow; C = light blue; G = green; U = red. (b) Comparison of complexes between Benzo(a)pyrene and RNA. (A) Complex with 3′ hairpin of human U65 snRNAs (PDB 2EUY); (B) complex with 3′ stem loop of human U4 snRNA. Each nucleotide is identified by a different color: A = yellow; C = light blue; G = green; U = red.
