The known nucleotide sequence of Escherichia coli 16S ribosomal RNA has been converted to amino acid sequences in all possible ways, and compared to known ribosomal protein sequences. The degree of similarity is precisely what one would expect by chance alone, providing additional evidence that ribosomal proteins cannot be coded for by ribosomal RNA.
