Asymmetric Unit(hide GO term definitions)
Chain A,B   (NUSG_THEMA | P29397)
biological process
    GO:0006354    DNA-templated transcription, elongation    The extension of an RNA molecule after transcription initiation and promoter clearance at a DNA-dependent RNA polymerase promoter by the addition of ribonucleotides catalyzed by an RNA polymerase.
    GO:0006353    DNA-templated transcription, termination    The cellular process that completes DNA-templated transcription; the formation of phosphodiester bonds ceases, the RNA-DNA hybrid dissociates, and RNA polymerase releases the DNA.
    GO:0032784    regulation of DNA-templated transcription, elongation    Any process that modulates the frequency, rate or extent of transcription elongation, the extension of an RNA molecule after transcription initiation and promoter clearance by the addition of ribonucleotides catalyzed by a DNA-dependent RNA polymerase.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0031564    transcription antitermination    Regulation of transcription by a mechanism that allows RNA polymerase to continue transcription beyond termination site(s).
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
