WebThe trp operon consists of ________ genes that encode tryptophan biosynthesis enzymes. A One. B Two. C Three. D Four. E Five. 0 Comments 5 Problem Under what conditions does the trp repressor block transcription of the trp operon? A When the repressor binds to the inducer. B When the repressor binds to tryptophan. C WebThe trp operon consists of a regulatory gene, a promoter, an operator, and a terminator. The trp operon is active only when cellular tryptophan is scarce. If there isn't enough tryptophan, the repressor protein breaks off from the operator (where the repressor is normally bound) and RNA polymerase can complete its reading of the strand of DNA.

What is trp operon transcription? - Studybuff

WebThe five genes that are needed to synthesize tryptophan in E. coli are located next to each other in the trp operon. When tryptophan is plentiful, two tryptophan molecules bind the repressor protein at the operator sequence. This physically blocks the RNA polymerase from transcribing the tryptophan genes.
