Figure 2. Predicted secondary structure for the small ribosomal RNA gene subunit (rrnS) in B. procyonis mtDNA.

Base-pairing is indicated as follows: Watson-Crick pairs by lines, wobble GU pairs by large dots and other non-canonical pairs by small dots. Conserved secondary structure elements are denoted by bold numbers (1–48) [29]. Binding sites for the amino-acyl trn (A) or peptidyl-transferase (P) [54] are indicated by lines.
