#Question id: 2632


How would transcription of the E. coli trp operon be affected,

I. If Removing sequence 4;

II. Changing several nucleotides in sequence 3 so that it can base-pair with sequence 4 but not with sequence 2;

#SCPH01 Biochemistry
  1. I-No attenuation of transcription.

  2. I & II- The only regulation would be that afforded by the Trp repressor.

  3. II-Constant attenuation of transcription. Attenuator always forms, regardless of the availability of tryptophan.

  4. Only A & C
