    6360   Transcription From RNA Polymerase I Promoter  The Synthesis of RNA From a DNA Template by RNA Polymerase I (rnap I) Originating At an Rnap I Promoter. 
    6366   Transcription From RNA Polymerase Ii Promoter  The Synthesis of RNA From a DNA Template by RNA Polymerase Ii Originating At an RNA Polymerase Ii Promoter. Includes Transcription of Messenger RNA (mrna) and Certain Small Nuclear Rnas (snrnas). 
    6383   Transcription From RNA Polymerase Iii Promoter  The Synthesis of RNA From a DNA Template by RNA Polymerase Iii Originating At an Rnap Iii Promoter. 
    42254   Ribosome Biogenesis  A Cellular Process That Results in the Biosynthesis of Constituent Macromolecules Assembly and Arrangement of Constituent Parts of Ribosome Subunits; Includes Transport to the Sites of Protein Synthesis. 
    42797   TRNA Transcription From RNA Polymerase Iii Promoter  The Synthesis of Transfer RNA (trna) From a DNA Template by RNA Polymerase Iii (pol Iii) Originating At a Pol Iii Promoter. 
    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. 
    5654   Nucleoplasm  That Part of the Nuclear Content Other Than the Chromosomes or the Nucleolus. 
    5665   DNA Directed RNA Polymerase Ii Core Complex  RNA Polymerase Ii One of Three Nuclear DNA Directed RNA Polymerases Found in All Eukaryotes Is a Multisubunit Complex; Typically It Produces Mrnas Snornas and Some of the Snrnas. Two Large Subunits Comprise the Most Conserved Portion Including the Catalytic Site and Share Similarity with Other Eukaryotic and Bacterial Multisubunit RNA Polymerases. the Largest Subunit of RNA Polymerase Ii Contains an Essential Carboxyl Terminal Domain (ctd) Composed of a Variable Number of Heptapeptide Repeats (ysptsps). the Remainder of the Complex Is Composed of Smaller Subunits (generally Ten or More) Some of Which Are Also Found in RNA Polymerases I and Iii. Although the Core Is Competent to Mediate Ribonucleic Acid Synthesis It Requires Additional Factors to Select the Appropriate Template.
