Which of the following occurs as a result of an abundance of tryptophan in E. coli? View Available Hint(s) Which of the following occurs as a result of an abundance of tryptophan in E. coli? The leader sequence is not transcribed. Stalling of the ribosome at trp codons in the leader sequence The 5 trp genes (TrpA – TrpE) are not transcribed. The 5 trp genes (TrpA – TrpE) are transcribed, but not translated. Submit Part B Which of the following features of the trp operon is likely least essential to the process of attenuation? View Available Hint(s) Which of the following features of the trp operon is likely least essential to the process of attenuation? The order of the structural genes, E, D, C, B, A Transcription and translation of the leader sequence occur simultaneously. Trp codons near the beginning of the leader sequence The ability of sequences within the leader mRNA to pair with one another Submit Part C Attenuator systems such as the one described for regulation of tryptophan synthesis would be just as likely to occur in eukaryotes as in prokaryotes.
