When you add a small amount of the signal peptide to the flask containing a population of E. Luminescent, what will be the result? Discuss the levels of GB protein, signal peptide, and the status of the transcription factors in your answer.2.Explain the levels of transcription for both GB and the signal peptide when there is no signal peptide present. Use terms such as repressor and activator in your answer.3.Predict the phenotype of the bacterium containing a mutated repressor such that it could no longer bind to the DNA.4.Predict the phenotype for the bacterium containing a mutated activator such that it could no longer bind to the GB protein.
