At the Transcriptional Level, How Does Tryptophan Control the Production

question 3

Multiple Choice

At the transcriptional level, how does tryptophan control the production of genes within the trp operon?

• A)the trp repressor contains a high percentage of Trp residues and is thus only produced when Trp levels are high
• B)without sufficient Trp, the production of the trp repressor is truncated, thus producing a protein that cannot bind to the operon, ultimately resulting in structural gene expression
• C)high levels of Trp cause the repressor to be proteolytically digested
• D)the trp repressor binds to the operon only when bound to Trp
• E)none of the above
