  6. Two DNA strands must separate for _______ to occur.
    transcription
  7. A _______ is a specific DNA sequence that signals the beginning of a gene/ where to start transcribing a gene.
    promoter
  8. A binding site for RNA _________ and determines which of the 2 strands of the DNA double helix is used as the template in transcription.
    polymerase
  9. A _________ is a specific DNA sequence that signals the end of a gene/ where to stop transcribing a gene

  10. The RNA nucleotides are linked by the transcription enzyme _______ ________, which catalyzes the reaction.
    RNA polymerase
  11. What are the 3 Phases of Transcription
