even though purified uracil-deoxyribonucleic acid glycosylase excised 5-fluorouracil from deoxyribonucleic acid at only 5 % the rate with which it excised uracil , most of the 5-fluorouracil excised from deoxyribonucleic acid in vivo was apparently excised directly by uracil-deoxyribonucleic acid glycosylase rather than by repair initiated by excision of uracil .
