Question
In an operon, the repressor binds to the _______.
ANSWER: promoter
, operator
, inducer
, genes
Solution
To answer the question regarding where the repressor binds in an operon, it's essential to understand the function of each component involved in the operon model.
Key Components of an Operon:
- Promoter: A region where RNA polymerase binds to initiate transcription.
- Operator: A segment of DNA that is bound by the repressor, which regulates transcription.
- Inducer: A molecule that can inactivate the repressor, allowing transcription to occur.
- Genes: Sequences that encode proteins.
Correct Answer
The repressor binds to the operator in an operon. This binding prevents transcription of the downstream genes by blocking RNA polymerase from accessing the promoter region.
Therefore, the complete response to your question is:
The repressor binds to the operator.
