- - - - initial nucleotide strand
      - Synthesized by primase
- - - - responsible for the first level of packing in chromatin
- - - - the sub units run in opposite directions
- - - - Reading frame
        
        correct groupings for the specified polypeptide
- - - - occurs in the cytoplasm
    - - occurs in the cytoplasm
    - - elongation
      - termination
      - initiation
  - - - occurs in the cytoplasm
    - - occurs in the nucleus
    - - Elongation
        
        Nucleotides are added to the 3' and of the growing RNA molecule
      - Termination
        
        Bacteria
        
        polymerase stops transcription at the end of the terminator and mRNA can be translated without further modification
        
        Eukaryotes
        
        RNA poly2 transcribes the polydenylation signal sequence; RNA transcript is released 10-35 nucleotides past this sequence
      - Initiation
        
        Promoters signal the transcription start point
        
        Transcription factors
        
        mediate binding of RNA polymerase and initiation of transcription
        
        TATA box
        
        promoter that forms the initiation complex in eukaryotes
