Question

Q2G: Knowing how the ara operon is being regulated when both Arabinose and Glucose are
present, which of the following conclusions can you make based on your results? Select all that apply (2 marks).
(a) The level of transcription of the PGLO plasmid DNA decreases as the concentration of
Glucose increases. (answer)
(b) The concentration of Arabinose does not affect transcription since A0G3 and A3G3 show
similar fluorescence intensity.
(c) The level of transcription of the PGLO plasmid DNA increases as the concentration of
Glucose increases.
(d) When glucose is low and arabinose is high, cAMP is high-high levels of CAMP-CAP-
facilitates/enhances/promotes transcription of ara operon. (answer)
