Question
- Name the molecule 'M' that binds with the operator.
- Mention the consequences of such binding.
- What will prevent the binding of the molecule 'M' with the operator gene? Mention the event that follows.
✓
Answer
- M is the repressor.
- When the repressor binds to the operator, transcription of structural genes by RNA-polymerase is prevented.
- An inducer can prevent the binding of repressor to operator.
- Consequently, the RNA-polymerase gets access to the promoter and transcription proceeds.
