EOG8WDGS4 GO:0005634 12/12 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] EOG8WDGS4 GO:0006352 12/12 DNA-templated transcription, initiation biological_process "Any process involved in the assembly of the RNA polymerase preinitiation complex (PIC) at the core promoter region of a DNA template, resulting in the subsequent synthesis of RNA from that promoter. The initiation phase includes PIC assembly and the formation of the first few bonds in the RNA chain, including abortive initiation, which occurs when the first few nucleotides are repeatedly synthesized and then released. The initiation phase ends just before and does not include promoter clearance, or release, which is the transition between the initiation and elongation phases of transcription."

[GOC:dph, GOC:jl, GOC:tb, GOC:vw] EOG8WDGS4 GO:0016570 12/12 histone modification biological_process "The covalent alteration of one or more amino acid residues within a histone protein." [GOC:krc]
