Included Quiz Questions
Two 6-base sequences are present in bacterial promoters: TATAAT at the -10 position and TTGACA at the -35 position. What is the significance of these two base sequences being different? (Select all that apply)
- It allows for the location of the start site and the direction of transcription to be identified.
- It allows RNA polymerase to distinguish between the template strand and the coding strand of the DNA molecule.
- They are individual binding sites for both the core polymerase and the holoenzyme.
- They are individual binding sites for both the holoenzyme and ATP.
- They allow extra proteins to attach to DNA polymerase to form a holoenzyme.
Which of the following is the most accurate definition of a promoter?
- A DNA sequence to which proteins bind to start transcription
- A regulator region on the 5' end of a template strand of DNA where RNA polymerase binds to initiate transcription
- A regulator region on the 3' end of a template strand of DNA where RNA polymerase binds to initiate transcription
- A regulator region on the 3' end of a gene where DNA polymerase binds to initiate replication
- A regulator region on the 3' end of a coding strand of DNA where RNA polymerase binds to initiate transcription
