He gave me the experience to learn about the pharmaceutical industry .The work … 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…

WebThe repressor will then bind to the operator, stopping the manufacture of lactase. In molecular genetics, a repressor is a DNA- or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers. A DNA-binding repressor blocks the attachment of RNA polymerase to the promoter, thus ...

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.

WebTranscription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA. Transcription factors that are activators boost a gene's transcription. Repressors decrease transcription. Groups of transcription factor binding sites called enhancers and silencers can turn a gene on/off in specific parts of the body.
