title: [Presence in the composition of bacterial DNA of covalently bound RNA fragments].
abstract: The nucleotide composition of chromosome and plasmid DNA free of hybrid RNA isolated from resting Escherichia coli cells preliminary cultivated with the help of [14C] uracil has been studied. It has been established that DNA contains [14C]uracil side by side with adenine, thymine, guanine and cytosine. It confirms the presence of RNA fragments in the composition of bacterial DNA which are connected with it covalently.
