title: Deoxyribonucleic acid-ribonucleic acid hybridization studies on the L-Arabinose operon of Escherichia coli B-r.
abstract: An increase in the rate of synthesis of ara-specific messenger ribonucleic acid as measured by deoxyribonucleic acid-ribonucleic acid hybridization has been detected in the induced wild-type (ara(+)) strain of Escherichia coli B/r as compared with the uninduced control, thus providing evidence that regulation of the positively controlled l-arabinose operon is at the level of transcription.
