If the gene encoding the trp repressor is mutated such that it can no longer bind tryptophan, Will transcription of the trp operon occur?
  • a)
    Yes, because the trp repressor can only bind the trp operon and block transcriptional initiation when it is bound to tryptophan. 
  • b)
    No, because this mutation does not affect the part of the repressor that can bind the operator.
  • c)
    No, because the trp operon is repressed only when tryptophan levels are high.
  • d)
    Yes, because the trp operon can allosterically regulate the enzymes needed to synthesise the amino acid tryptophan.
Correct answer is option 'A'. Can you explain this answer?

If there pressor can no longer bind tryptophan, then it cannot bind the operator and transcription of the trp operon will always be on, whether tryptophan levels in the cell high or low.
