Explain whether the lac operon would be transcribed in a mutant that is completely missing the EIIA^GLC gene. Include your reasoning.
Answer :
It could transcribe. If there is no glucose concentration of CAMP rises binding to CAP and activation of operon and CAMP. CAP protein binds to the DNA and starts DNA transcriptional activity.
EIIA accumulated and activates adenylate transferase most of the times EIIA are dephosphorylated and this allows it to inhibit adenylate cuclase, glycerol kinase, lactose permeases so these activities will be interrupted but the transcription will happen using a different pathway.
