the ability to label and recovery selectively the newly synthesized polynucleotides by incubating cells with inorganic thiophosphate complements earlier findings [ sun , i. y.-c. & allfrey , v. g. ( 1982 ) j. biol . chem , 257 , 1347 -- 1353 ] that thiophosphate enters intracellular nucleotide pools and serves as an effective precursor for the phosphorylation of nuclear proteins in vivo .
