EOG89W4X4 GO:0005634 11/11 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."

An example is the suppression by cells with a particular fate of the adoption of the same fate by surrounding cells." [GOC:bf, GOC:kmv]
