Gene Regulation In Prokaryotes - Trp Flashcards
1
Q
Trp
A
Repressive operon
2
Q
Operator Location
A
Between the promoter regions and the first trp-coding gene
3
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
4
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
5
Q
Function
A
Regulation of tryptophan production
