Answer 1

Here are the corrected sentences:

1. The operon contains a promoter and an operator.
2. The operator controls whether RNA polymerase can advance along the DNA strand or not.
3. The promoter is the region of DNA where RNA polymerase initially binds.
4. If the repressor is not bound to the operator, then RNA polymerase can transcribe the structural genes.
5. The operon operates differently depending on whether the operon is inducible or repressible.
6. If the repressor is bound to the operator, then RNA polymerase cannot transcribe the structural genes.
7. Inducers increase expression of the structural genes. This typically occurs in response to the presence of a substrate.
8. An operon controls the expression of functionally related genes and consists of a control region and structural genes.
9. Repressors decrease expression of the structural genes. This typically occurs in response to an absence of a substrate.
