Suppose the two tryptophan codons within the leader peptide of the trp operon were changed from tryptophan to asparagine. Predict if attenuation (premature termination of transcription) of the trp operon will occur if bacteria are grown on media containing:(a) high tryptophan, high asparagine.(b) high tryptophan, low asparagine.(c) low tryptophan, high asparagine.(d) low tryptophan, low asparagine.
