It is important to keep in mind the difference between rRNA genes and 
protein coding genes.  THe primary structure of the rRNA gene is a
nucleotide seqeunce and the interaction between primary and secondary
structure is direct.  Protein genes are translated into another medium.
Here the phenotypic secondary structure is determined by teh resulting
amino acid sequence.
