two polynucleotide binding sites have been detected on s1 : site i binds either single-stranded dna or rna and does not discriminate between adenine- and cytidine-containing polynucleotides , while the ii binding is highly specific for rna over dna and shows a marked preference for cytidine polynucleotides over the corresponding adenine-containing species .
