WebMeaning and definition of operator : In prokaryotic DNA, a sequence of nucleotides near the start of an operon to which an active represser can attach. The binding of the represser … The term "operon" was first proposed in a short paper in the Proceedings of the French Academy of Science in 1960. From this paper, the so-called general theory of the operon was developed. This theory suggested that in all cases, genes within an operon are negatively controlled by a repressor acting at a single operator located before the first gene. Later, it was discovered that genes could be positively regulated and also regulated at steps that follow transcription initiation…
