EOG8MD0H8 GO:0005634 1/3 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] EOG8MD0H8 GO:0006351 1/3 transcription, DNA-templated biological_process "The cellular synthesis of RNA on a template of DNA." [GOC:jl, GOC:txnOH] EOG8MD0H8 GO:0003677 1/3 DNA binding molecular_function "Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid)." [GOC:dph, GOC:jl, GOC:tb, GOC:vw] EOG8MD0H8 GO:0003899 1/3 DNA-directed RNA polymerase activity molecular_function "Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template, i.e. the catalysis of DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'." [EC:2.7.7.6]
