An operon is basically a group of genes all under control of one promoter. Thepromoter is the sequence where the RNA polymerase binds and begins transcription. It is upstream of the sequence encoding the protein. An operator is a regulatory sequence that a repressor can bind to.

Operators are where transcription factors bind to the DNA to prevent transcription. Operons are regions of DNA that contain clusters of related genes. They are made up of a promoter region, an operator, and multiple related genes. The operator can be located either within the promoter or between the promoter and the genes.

The idea of operator is associated with but not identical to that of operon. From , pp. 8 and 9: We will often say that a particular regulatory protein binds to a specific operator site (or sites) on a DNA molecule. We mean by this that the protein is usually to be found there, but that it can quite readily (and often does) fall off that site.

Operator Definition An operator is a genetic sequence which allows proteins responsible for transcription to attach to the DNA sequence. The gene, or genes, which get transcribed when the operator is bound are known as the operon. Repressor proteins, which bind to the gene operator, can block transcription factors from binding to the operator.

We mean by this that the protein is usually to be found there, but that it can quite readily (and often does) fall off that site. The operator (O), comprising a short segment of DNA found adjacent to the promoter is a control element which binds a regulator protein that can either repress or activate transcription.
