Q

High tryptophan concentration & effect

A

Tryptophan binds to repressor protein
-> Repressor-protein binds to operator, blocking RNA polymerase II from transcribing the trp genes

Q

Low tryptophan concentration & result

A

No binding of tryptophan to repressor protein
-> repressor protein dissociates from operator, allowing RNA polymerase to transcribe trp gene
