Term
|
Definition
| Sequence of DNA where the RNA polymerase attaches to begin transcription |
|
|
Term
|
Definition
| Controls the access of RNA polymerase to the genes. It is where the repressor attaches |
|
|
Term
|
Definition
| Contain DNA sequences that code for enzymes produced by the operon |

Definition
Controls the breakdown of lactose
A repressible operon
Anabolic - builds molecules
Is turned off but when lactose is present it binds to the repressor so the repressor can not bind to the operator. Then RNA polymerase can do transcription to make lactase to breakdown lactose |

Definition
Makes the amino acid tryptophan
A repressible operon
Anabolic - builds molecules
RNA polymerase does transcription and makes tryptophan. If there is too much tryptophan, so of the tryptophan binds to the repressor and this allows it to bind to the operator and the RNA polymerase is blocked |
|
|
Term
|
Definition
| the active repressor binds to the operator region, which prevents transcription |
