Definitions:

Regulatory Sequences

DNA sequences that are involved in controlling the expression of genes, determining when and where genes are turned on or off.

Repressible Operon

An operon that is normally active, but can be controlled by a repressor protein, which becomes active when it binds to a corepressor; the active repressor binds to the operator, making the operon transcriptionally inactive. Compare with inducible operon.

Inactive Repressor

A protein that does not suppress gene expression, often because it has not been activated by a specific signal or molecule.

Precursor Product

A relationship in biochemical processes where a precursor molecule is transformed into a product through metabolic reactions.
