hybridization of single strands of plasmid deoxyribonucleic acid with in vivo-labeled ribonucleic acid from proteus mirabilis containing nr1 indicated that transcription within the rtf-tc component is from the nr1 strand which preferentially binds polyuridylic acid-polyguanidylic acid , whereas transcription within the r-determinants component is predominantly from the complementary strand .
