we have compared more than 200 nucleotides of the d. virilis 28s rrna gene with sequences of homologous regions of rdna in tetrahymena pigmentosa ( wild and sommer , 1980 ) and xenopus laevis ( gourse and gerbi , 1980 ) : there is 93 % sequence homology among the diverse species , so that the rdna region in question ( about two-thirds of the way into the 28s rrna coding sequence ) has been very highly conserved in eukaryote evolution .
