To determine which of the options is not induced in the operon model, we need to understand the roles of each component.

1. Regulator gene: This gene codes for the production of a repressor protein. It is not directly involved in the induction process.

2. Operator: This is a region of DNA located near the promoter site. It acts as a binding site for the repressor protein and helps regulate the expression of the structural genes.

3. Repressor: This protein is produced by the regulator gene and can bind to the operator. When bound, it prevents the RNA polymerase from transcribing the structural genes, thus inhibiting their expression.

4. Structural gene: These genes code for the production of specific proteins or enzymes. They are the target of the operon model and can be induced or repressed based on the presence or absence of inducers or repressors.

Based on this information, the option that is not induced in the operon model is the regulator gene.
