our results lead us to conclude that these lesions are ( 1 ) cytosine hydrates , which code for cytosine and to a lesser extent thymine , ( 2 ) uracil hydrates , which code for adenine and are not sensitive to uracil dna glycosylase , and ( 3 ) uracils , which code for adenine and are removed by uracil dna glycosylase .
