WebSep 9, 2024 · What are operators class 12 biology? Operator is the regulatory region overlapping the promoter of the lac operon. Repressor protein binds to the operator and inhibits binding of RNA polymerase to the promoter site. This way it acts as a negative regulatory site and inhibits transcription initiation of the lac operon in E. coli. WebMar 5, 2024 · The operator is a region of the operon where regulatory proteins bind. It is located near the promoter and helps regulate transcription of the operon genes. The Lac …

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…
