The intervening sequence of the ribosomal RNA gene is highly conserved between two Tetrahymena species.
The entire intervening sequence of Tetrahymena thermophila ribosomal DNA has been determined. It is 413 nucleotides long and has the same splice junctions as those in T. pigmentosa. There is 93% homology between the intervening sequences in the two species, and 100% homology between their adjacent 26S RNA coding regions.
