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.
