Indicate whether each of the following statements about regulatory proteins is true or false.
1. Regulatory proteins control transcription initiation by modulating the ability of DNA polymerase to bind to the promoter.
2. Regulatory proteins function by binding to specific sequences on the DNA called regulatory sequence.
3. Hundreds of regulatory sequences have been identified and each one provides a binding site for a specific protein that is able to recognize the sequence.
4. In order to recognize and bind to the correct regulatory sequence, a regulatory protein must unwind and separate the two strands of the DNA double helix.
5. Binding of a regulatory protein to DNA either inhibits transcription by getting in the way of RNA polymerase or stimulates transcription by favoring the binding of RNA polymerase to the promoter.
6. Repressors are regulatory proteins that bind to RNA polymerase and act to prevent or decrease the initiation of transcription.
7. Activators are regulatory proteins that bind to enhancers and act to stimulate the initiation of transcription.
