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.
与未诱导的对照相比,通过脱氧核糖核酸-核糖核酸杂交检测到,在诱导的大肠杆菌B/r野生型(ara(+))菌株中,阿拉伯糖特异性信使核糖核酸的合成速率有所增加,从而提供了证据表明正调控的L-阿拉伯糖操纵子的调控发生在转录水平。
