Tryprophan Operon: set of genes in E. coli that allows for the synthesis of tryptophan
: continuously transcribed at low [Trp]
: at high [Trp], the operon is repressed since Trp is readily available and need not be synthesized
Arrange the following steps of the regulation of the trp operon in order of occurrence.
__ The trp repressor protein binds to the operator.
__ Levels of tryptophan rise and more is required.
__ Tryptophan binds to trp repressor protein and induces a conformational change.
__ Products of the trp gene synthesize tryptophan.
__ RNA polymerase binds to the promotor allowing transcription of the trp genes to proceed.
__ The trp repressor protein blocks RNA polymerase from binding to the promotor.
