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.Operon.

One of the most influential factors in determining a team’s success...Trp operon. The Trp operon plays a crucial role in tryptophan production, an essential amino acid. In E. Coli, the operon consists of genes and regulatory DNA sequences, including the promoter and operator.

Gene regulation is the process of controlling which genes in a cell's DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA.
