Question: The 3-4 stem-loop and U-rich attenuator found in the trp operon (see Figure 14.12) is an example of p-independent termination. The function of p-independent terminators

The 3-4 stem-loop and U-rich attenuator found in the trp operon (see Figure 14.12) is an example of p-independent termination. The function of p-independent terminators is described in Chapter 12. Would you expect attenuation to occur if the tryptophan levels were high and mutations changed the attenuator sequence from UUUUUUUU to UGGUUGUC? Explain why or why not.
