    Chain A
    GO ID   Ontology GO Term Definition
    6352   DNA Templated Transcription Initiation  Any Process Involved in the Assembly of the RNA Polymerase Preinitiation Complex (pic) At the Core Promoter Region of a DNA Template Resulting in the Subsequent Synthesis of RNA From That Promoter. the Initiation Phase Includes Pic Assembly and the Formation of the First Few Bonds in the RNA Chain Including Abortive Initiation Which Occurs When the First Few Nucleotides Are Repeatedly Synthesized and Then Released. the Initiation Phase Ends Just Before and Does Not Include Promoter Clearance or Release Which Is the Transition Between the Initiation and Elongation Phases of Transcription. 
    6355   Regulation of Transcription DNA Templated  Any Process That Modulates the Frequency Rate or Extent of Cellular DNA Templated Transcription. 
    8270   Zinc Ion Binding  Interacting Selectively and Non Covalently with Zinc (zn) Ions.
