Operons Flashcards
1
Q
Define Operon
A
A cluster or series of related genes (share a common goal)
2
Q
Promoter
A
Where RNA polymerase attaches to DNA sequence for transcription
3
Q
Operator
A
Where repressor attaches to DNA sequence to BLOCK transcription
4
Q
Inducer
A
Inactivates the repressor and removes it from the DNA (lactose is the inducer)
5
Q
Repressor
A
Attaches to the operator and blocks RNA polymerase from transcribing mRNA
6
Q
What happens if: a mutation is found in repressor protein?
A
Repressor protein cannot bind to operator
