According to the operon model, for the synthesis of an inducible enzyme to occur, the repressor must not bind to the operator.

Here's a step-by-step explanation:

1. The operon model is a system for gene regulation, primarily observed in prokaryotes. It involves a series of genes including structural genes, a promoter gene, an operator gene, and a regulator gene.

2. The regulator gene produces a protein known as a repressor. The repressor binds to the operator gene, preventing transcription of the structural genes and thus, preventing the synthesis of the enzyme.

3. In the case of an inducible enzyme, the presence of a specific substance (inducer) prevents the repressor from binding to the operator.

4. When the inducer is present, it binds to the repressor, changing its shape and making it unable to bind to the operator.

5. This allows the RNA polymerase to move along the structural genes, transcribing them and leading to the synthesis of the enzyme.

So, for the synthesis of an inducible enzyme to occur, the repressor must not bind to the operator.
