Measurements of the time required for transcription of regions of known genetic length in the tryptophan operon of Escherichia coli indicate that there are no major unidentified structural genes in the operon either before the operator proximal E gene or after the operator distal A gene.
对大肠杆菌色氨酸操纵子中已知基因长度区域转录所需时间的测量表明,在操纵基因近端的E基因之前或操纵基因远端的A基因之后,该操纵子中不存在主要的未鉴定结构基因。
