Verified
Repressible genes typically regulate gene expression of enzymes involved in anabolic pathways.
Repressible Genes
Genes whose expression is decreased or stopped in response to the presence of a specific molecule, usually an end product of a metabolic pathway.
Anabolic Pathways
Metabolic pathways that construct molecules from smaller units, requiring energy, commonly associated with growth and development.

Final Answer :
True
Explanation :
Repressible genes are often involved in anabolic pathways where the end product of the pathway can act as a corepressor, binding to a repressor protein and activating it to bind to the operator site, thereby inhibiting the transcription of genes involved in the pathway. This is a feedback inhibition mechanism to regulate the synthesis of substances the cell currently has in sufficient quantities.
