RESUMO
Phages lambda and fd were propagated in Escherichia coli strains that have either host K-12 or the N-3 R-factor deoxyribonucleic acid-cytosine methylase activity. Pyrimidine tracts containing 3H-labeled 5-methylcytosine (MeC) were analyzed; in all cases, the major methylated sequence was 5' ... C-MeC-T ... 3'.
