Practice questions

1 of 21Practice questions for this set
In bacteria, gene R is transcribed from a promoter that requires an activator bound upstream to help recruit RNA polymerase. Under low oxygen, the activator binds DNA and transcription increases. A point mutation occurs in the activator's DNA-binding domain so it cannot bind the upstream site, but the promoter sequence is unchanged. Which result is most likely under low oxygen?
