"The ordered and organized complex of DNA and protein that forms the chromosome [goid 785] [pmid 9891037] [evidence NAS]; Either of the ends of a spindle, where spindle microtubules are organized; usually contains a microtubule organizing center and accessory molecules, spindle microtubules and astral microtubules [goid 922] [pmid 7542657] [evidence IDA]; The region of a condensed chromosome kinetochore most external to centromeric DNA; this outer region mediates kinetochore-microtubule interactions [goid 940] [pmid 12974617] [evidence TAS]; The region of a condensed chromosome kinetochore most external to centromeric DNA; this outer region mediates kinetochore-microtubule interactions [goid 940] [pmid 7904902] [evidence IDA]; The region of a condensed chromosome kinetochore most external to centromeric DNA; this outer region mediates kinetochore-microtubule interactions [goid 940] [pmid 7542657] [evidence IDA]; 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 [goid 5634] [pmid 7642639] [evidence IDA]; A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated.
