7 Activities

In a prokaryotic cell there is high levels of the amino acid tryptophan. Which of the following would be occurring in this cell?

  2. The leader sequence will be translated quickly
  3. A hairpin loop will form between leader sequences 3 and 4 causing transcription termination
  4. Transcription of the trp operon will be off
