TRP Operons

Front

What type of system is a TRP Operon an example of?

Back

Repressible system

Front

What is a repressible system?

Back

A system where the operon is automatically turned on unless a repressor becomes active and turns it off.

Front

Is the TRP Operon a negative or positive feedback loop?

Back

Negative feedback loop

Front

Is the TRP Operon normally ON or OFF?

Back

On

Front

Why would the tryptophan stop being produced?

Back

The repressor protein binds to the operator when tryptophan levels are high.

Front

What is the role of the repressor protein in a TRP Operon?

Back

It binds to the operator to inhibit transcription when tryptophan is abundant.

Front

What happens to the TRP Operon when tryptophan levels are low?

Back

The repressor protein is inactive, allowing transcription to occur.

Front

What is the function of an operon in prokaryotic cells?

Back

It regulates the expression of genes involved in a specific metabolic pathway.

Front

How does feedback inhibition work in the context of the TRP Operon?

Back

High levels of tryptophan activate the repressor, stopping further production.

Front

What is the significance of the operator in an operon?

Back

It is the region where the repressor binds to control gene expression.
