Operon
A promoter region is different from an operator region in the sense that the operator region is where DNA binds, whereas the promoter region is the binding site for the RNA polymerase. These two different regions are essentially opposites.
operon. An operon is a unit of bacterial gene expression consisting of a promoter, an operator, and a cluster of genes that work together as a single transcriptional unit. The operator region controls the transcription of the genes within the operon in response to regulatory signals.
An operon is a group of genes that operate together.Operon- a functioning unit of genomic DNA containing a cluster of genes under the control of a single regulatory signal or promoter.Operons are clusters of genes consisting of one operator and promoter. There are a lac operon, which is responsible for metabolism of glucose. And there is also the Trp operon, which is responsible for synthesising tryptophan.
In eukaryotes, the TATA-binding protein (TBP) is involved in promoter recognition. TBP is a subunit of the transcription factor II D (TFIID) complex, which binds to the TATA box within the promoter region of genes and helps initiate transcription.
The "lac operon" is the unit of DNA in E.coli and other bacteria which is responsible for the metabolism of lactose. So with regards to the question above, its function is that of an operator.

Operon. It contains the promoter, operator, and the structural gene.

TFIID
Its involved in promoter specifictiy in DNA transcription
The main function of a promoter is to bring attention of an event to the public. Boxing promoters, for example, are adept at hyping fights to heighten interest.

A repressor protein turns off transcription by binding to the operator region. By binding to the operator, the repressor prevents the RNA polymerase from binding to the promoter region and initiating transcription. This prevents the expression of the gene or genes downstream of the operator.
