ultraviolet irradiation ( lambda = 254 nm ) of the 30-s subunit does not result in the covalent cross-linking of s1 with 16-s rna at irradiation doses up to 150 quanta/nucleotide , whereas the irradiation under the same conditions of s1 . polynucleotide complexes [ s1 . poly ( u ) , s1 . poly ( a ) and s1 . q beta phage rna ] induces effective formation of polynucleotide-protein cross-links .
