Question

Which statement about operons is TRUE?

Inducible operons function Catabolically & Repressible operons function Anabolically

Inducible operons function Anabolically & Repressible operons function Catabolically

Both types are used for Anabolic needs

Both types are used for Catabolic needs

Operon activity has nothing to do with synthesis or breakdown of molecules in a cell

Inducible operons function Catabolically & Repressible operons function Anabolically

Inducible operons function Anabolically & Repressible operons function Catabolically

Both types are used for Anabolic needs

Both types are used for Catabolic needs

Operon activity has nothing to do with synthesis or breakdown of molecules in a cell

Explanation / Answer

The Operon is considered as a genetic functional unit in bacteria.Operons, where gene activity is repressed upon addition of a chemical are known as repressed operons. Repressed operons often work anabolic ally where end product is feedback inhibitor of transcription.e.g tryptophan operon.

However, in operons where. gene activity is induced upon addition of chemical are known as induced operons. Induced operons often work catabolic ally where enzymes involved in catabolism are not synthesized unless their substrates are present.e.g lac operon.

So the correct option is (A) Inducible operons function Catabolically & Repressible operons function Anabolically
