Question

Please help!!!

Inside a prokaryote, such as E. coli, an operon controls for the production of the amino acid tryptophan. What occurs in the cell in order to turn off the production of tryptophan?

Tryptophan binds with the promoter to block the DNA polymerase.
The operon binds to the RNA polymerase and releases the repressor.
Tryptophan binds with the repressor, allowing it to attach to the operator site, blocking RNA polymerase.
The RNA polymerase binds to the tryptophan, activating the repressor, blocking the promoter.

Answer 1

i am not 100% sure, but with all my knowledge (i am pretty sure about this, not 100%) i think it would be c

Answer 2

Answer: Option C

Step-by-step explanation:

Lac operon can control the production of amino acids in the Prokaryotic organism such as E.coli.

The tryptophan binds to the trp repressor molecule and leds to the conformational change converting into active form.

The repressor molecule bounds the tryptophan which attaches to the operator and which blocks the RNA polymerase from binding to the promoter region thus preventing transcription.
