hybridization experiments with l. brasiliensis ( y ) dna showed that both rna types compete equally well for the ribosomal sites in this dna , and that l. brasiliensis ( y ) rrna recognizes the ribosomal sites in dna of trypanosoma cruzi ( ep ) , thus indicating that no gross changes occurred in their nucleotide sequences during evolution .
