Consider the leader region of the trp mRNA. How would transcription of the E. coli trp operon be affected by removing sequence 4?

A) increased attenuation and thus decreased transcription

B) decreased attenuation and thus increased transcription

C) no attenuation, and thus transcription would proceed at the maximum level

Solution

The answer is: C) no attenuation, and thus transcription would proceed at the maximum level.

Sequence 4 is the attenuator, so removing of sequence 4 will stop the attenuation process of trp operon.
