We have determined the nucleotide sequence of the 26S large subunit (LSU) rRNA genes for twoTetrahymena species,T. thermophila andT. pyriformis. The inferred rRNA sequences are presented in their most probable secondary structures based on compensatory mutations, energy, and conservation criteria. The majority of the nucleotide changes between the twoTetrahymena LSU rRNAs and the positions of a relatively large deletion and of the processing cleavage sites resulting in the generation of the… CONTINUE READING
