If the Trp codons in thetrpL gene were mutated to encode another amino acid, what would the result be? The trp operon would never be transcribed. Thetrp operon would always be transcribed. Thetrp operon would only be transcribed when tryptophan in the cell was low. Thetrp operon would only be transcribed when tryptophan in the cell was high.

Which RNA conformation favors transcription—the form with the antiterminator stem-loop or the form with the terminator stem-loop?
If a researcher moves the promoter for the lac operon to the region between the beta galactosidase (lacZ) gene and the permease (lacY) gene, which of the following results would you expect? A) The three genes of the lac operon will be expressed normally. B) The repressor will not be able to bind to the operon. C) The operon will still transcribe the lacZ and lacY genes, but the mRNA will not be translated. D) LacZ will not be transcribed and Beta galactosidase will not be produced.
The tryptophan operon of E. coli represents an example of a gene regulatory system which is: a repressible system (normally turned on, but can be repressed) a repressible system (normally repressed, but can be turned on) an activator system (normally turned off, but can be activated) an activator system (normally activated, but can be turned off) all of the above
Given the Table below concerning the lac operon, match the letter with what would be occurring for each scenario. Repressor is bound to the operator, cAMP complex is bound and transcription is prevented. Allolactose is bound to the repressor, cAMP complex is bound, and transcription is prevalent. Allolactose is bound to the repressor, cAMP complex is not assembled, and transcription is slow Repressor is bound to the operator, cAMP complex is not assembled, and transcription is prevented.
The trp operon is a repressible operon. A strain of e coli develops a mutation whereby the trp repressor protein can no longer bind to the operator. How will this effect the production of tryptophan producing enzymes? Will these bacteria be able to live in a tryptophan free media (bacteria food)?
A mutation at the operator prevents the regulator protein from binding.What effect will this mutation have in the following types of operons? Q. Regulator protein is a repressor of a repressible operon.
In the lac operon, the lacZ gene codes for an enzyme called ____________, which catalyze the breakdown of the sugar __________ into monosaccharides. This enzyme can also hydrolyze the sugar analog ____________, which produces blue pigments following its breakdown. Since the lac operon is not always on the bacterial cells, we add the chemical ________ which prevents the lac depressor from binding to the operators, leading to constitutive expression of the operon.
The promoter of an operon is the site to which RNA polymerase binds to begin transcription. Certain base changes in the promoter result in a mutant site that RNA polymerase can’t bind. Would you expect mutations in the promoter that prevents binding of RNA to act in trans on another copy of the operon on a plasmid or only in cis on the copy immediately adjacent to the mutated site?
