Explain the regulation of the trp operon by the 5' end of the mRNA when tryptophan is low vs high.

Explain how attenuation regulates the trp operon in response to cellular levels of tryptophan

This operon is also regulated by transcription attenuation. How does this attenuation work?

What is the function of the trp operon?

What is the function of the trp operon? What is tryptophan? What is an operon? What is a promoter? What is an operator? What is a repressor?

In the absence of trp, what happens to the genes within the trp operon? 1. regulator...

In the absence of trp, what happens to the genes within the trp operon? 1. regulator without tryp-binding prevents genes from transcribing. 2. regulator falls off the operator and structural genes get transcribed. 3. Lack of trp increases level of cAMP high, which leads to activation of CAP protein and gene expression. 4. active repressor binds to operator and genes do not get transcribed. 5. active activator binds to operator and transcription of the structural gene takes place.

In the trp operon, when trp levels are high, the ____________ stem-loop forms, and transcription of the structural genes ________________ . 1-3, continues 3-4, continues 2-3, continues 3-4, ends 2-3, ends

Which of the following statements about the tryptophan (trp) operon does not properly describe its function?...

Which of the following statements about the tryptophan (trp) operon does not properly describe its function? Select one: a. The trp operon is activated in the cell when tryptophan levels rise b. The enzymes expressed by the trp operon allow the cell to make tryptophan when cellular levels are low c. The trp operon is activated in the cell when tryptophan levels fall d. The trp repressor remains bound to the operon when allosterically bound by tryptophan in the...
