Predicted secondary structures of 22 mitochondrial tRNA sequences from the wild camel. All tRNAs were folded into secondary structures based on the "least free energy" principle. (A) 21 tRNAs exhibit cloverleaf structures and possess anticodons. The secondary structure of tRNAAsn was shown (bold) as an example for the cloverleaf structure that usually has 7 bp in the aminoacyl stems, 4 bp or 5 bp in the TψC and anticodon stems, and 4 bp or 3 bp in the DHU stems. tRNA stem regions include some non-complementary and T:G base pairings. (B) tRNAser can not form the appropriate dihydrouridine loop and does not possess the anticodon for AGN.
