WebTranscription initiation complex & looping. Combinatorial regulation. Key points: Transcription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA. Transcription factors that are activators boost a gene's transcription. Repressors decrease transcription. WebO The mutation will have no effect on transcription of the trp operon. The trp operon will be transcribed, unless tryptophan is supplied in the medium. A missense mutation in one of the enzymes encoded by the trp operon prevents a bacterial cell from producing tryptophan. What is the effect (if any) of this mutation on transcription of the trp ...
