EOG8N5Z9Z GO:0005634 8/41 nucleus cellular_component "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." [GOC:go_curators] EOG8N5Z9Z GO:0006355 8/41 regulation of transcription, DNA-templated biological_process "Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription." [GOC:go_curators, GOC:txnOH] EOG8N5Z9Z GO:0003723 1/41 RNA binding molecular_function "Interacting selectively and non-covalently with an RNA molecule or a portion thereof." [GOC:mah] EOG8N5Z9Z GO:0003964 1/41 RNA-directed DNA polymerase activity molecular_function "Catalysis of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). Catalyzes RNA-template-directed extension of the 3'- end of a DNA strand by one deoxynucleotide at a time." [EC:2.7.7.49]
