"+"=Wild-Type = Repressor Mutation (Unable to Bind Operator (Normal Function) | I- = Beta-Gal Mutation (Non-Functional) | I = Repressor Mutation (Unable to Bind Allolactose) = Promoter Mutation (No Transcription) 10° = Operator Mutation (Unable to Bind w/ Repressors) Wild-Type = | P+ O+Z+(One Copy) Nd Z- Prokaryotic Trp Operons - Bacteria (Disregard Attenuation) P- Answer Types: I = Low Levels * II = High Levels * III = Both High/Low * IV = Neither High/Low Q-/: Trp Operon attenuation shuts off what kind of transcription would take place and at high and/or tryptophan levels? Both vs. none? A) Non-mutated trp operon with an operator sequence mutation, repressors don't bind to operators. Would there be transcription of the trp operon in high or low tryptophan surroundings? Both vs. none? B) Non-mutated trp operon and a mutation in trpR gene that doesn't permit repressors to bind with operators; for transcription of trp operon, would it occur in high or low tryptophan environments? Both vs. none? C) Non-mutated trp operon with a trpR gene mutation. Would there be transcription of trp operon in a high or low tryptophan environment? Both vs. none? (Essentially, respressors won't bind to tryptophan).
