• What is a gene?
• What gene is responsible for the initiation of transcription?
• After RNA polymerase has bound to the promoter, it causes the DNA strands to? (this is the second element, make sure you know what this is called)
• RNA polymerase will continue to transcribe the DNA until it reaches a? (This is the third part)
