The trp operon is transcribed to synthesize the amino acid tryptophan. When tryptophan is present in the environment, the trp operon is NOT transcribed . On the other hand, when tryptophan is absent in the environment, the trp operon is transcribed . The trp operon is controlled by a(n) repressor protein through negative control .

Step-by-Step Analysis
The prompt describes the classic regulation of the trp operon in bacteria and provides four elements to evaluate.
Option 1: NOT transcribed. This aligns with the regulatory logic: when tryptophan is present, tryptophan acts as a corepressor that enables the repressor protein to bind to the operator and block transcription. Therefore, the operon is NOT transcribed in the ......Login to view full explanationLog in for full answers

Why does the introduction of a liver-specific "activator" protein into a skin cell not immediately cause the skin cell to start producing all liver-specific proteins?
Gene A is normally expressed in both liver cells and kidney cells. A patient is found to have a mutation in the regulatory region of Gene A. The clinical result is that Gene A is expressed at normal levels in the liver, but is completely absent in the kidney. Where is the mutation most likely located?
