    GO ID   Ontology GO Term Definition
    6355   Regulation of Transcription DNA Templated  Any Process That Modulates the Frequency Rate or Extent of Cellular DNA Templated Transcription. 
    6915   Apoptotic Process  A Programmed Cell Death Process Which Begins When a Cell Receives an Internal (e.g. DNA Damage) or External Signal (e.g. an Extracellular Death Ligand) and Proceeds Through a Series of Biochemical Events (signaling Pathway Phase) Which Trigger an Execution Phase. the Execution Phase Is the Last Step of an Apoptotic Process and Is Typically Characterized by Rounding Up of the Cell Retraction of Pseudopodes Reduction of Cellular Volume (pyknosis) Chromatin Condensation Nuclear Fragmentation (karyorrhexis) Plasma Membrane Blebbing and Fragmentation of the Cell Into Apoptotic Bodies. When the Execution Phase Is Completed the Cell Has Died. 
    5634   Nucleus  A Membrane Bounded Organelle of Eukaryotic Cells in Which Chromosomes Are Housed and Replicated. in Most Cells the Nucleus Contains All of the Cell's Chromosomes Except the Organellar Chromosomes and Is the Site of RNA Synthesis and Processing. in Some Species or in Specialized Cell Types RNA Metabolism or DNA Replication May Be Absent. 
    3677   DNA Binding  Any Molecular Function by Which a Gene Product Interacts Selectively and Non Covalently with DNA (deoxyribonucleic Acid). 
    3700   Sequence Specific DNA Binding Transcription Factor Activity  Interacting Selectively and Non Covalently with a Specific DNA Sequence in Order to Modulate Transcription. the Transcription Factor May or May Not Also Interact Selectively with a Protein or Macromolecular Complex. 
    44212   Transcription Regulatory Region DNA Binding  Interacting Selectively and Non Covalently with a DNA Region That Regulates the Transcription of a Region of DNA Which May Be a Gene Cistron or Operon. Binding May Occur As a Sequence Specific Interaction or As an Interaction Observed Only Once a Factor Has Been Recruited to the DNA by Other Factors.
