No statistically significant differences were detected in the base composition or sequence between the DNA of a wild and a mutant strain of the organism. 6-Methyl-aminopurine was found in the DNA of Serratia marcescens. The properties of this base and its N-nitroso derivative were compared with those of a synthetic sample., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-31-2-187
