5-Fluoropyrimidines and 5-azapyrimidines were found in our laboratory to be specific inhibitors of modification reactions taking place at the 5 position of pyrimidines in nucleic acids. Thus, 5-fluorouracil and 5-fluorouridine specifically inhibit the formation of 5-methyluracil, pseudouridine, and 5,6-dihydrouracil in
