| molecular function | 
|---|
|  | GO:0008017 |  | microtubule binding |  | Interacting selectively and non-covalently with microtubules, filaments composed of tubulin monomers. | 
|  | GO:0005515 |  | protein binding |  | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). | 
|  | GO:0019843 |  | rRNA binding |  | Interacting selectively and non-covalently with ribosomal RNA. | 
|  | GO:0043022 |  | ribosome binding |  | Interacting selectively and non-covalently with any part of a ribosome. | 
  | biological process | 
|---|
|  | GO:0048539 |  | bone marrow development |  | The process whose specific outcome is the progression of the bone marrow over time, from its formation to the mature structure. | 
|  | GO:0030282 |  | bone mineralization |  | The deposition of hydroxyapatite, a form of calcium phosphate with the formula Ca10(PO4)6(OH)2, in bone tissue. | 
|  | GO:0008283 |  | cell proliferation |  | The multiplication or reproduction of cells, resulting in the expansion of a cell population. | 
|  | GO:0001833 |  | inner cell mass cell proliferation |  | The proliferation of cells in the inner cell mass. | 
|  | GO:0030595 |  | leukocyte chemotaxis |  | The movement of a leukocyte in response to an external stimulus. | 
|  | GO:0042256 |  | mature ribosome assembly |  | The aggregation, arrangement and bonding together of the large and small ribosomal subunits into a functional ribosome. | 
|  | GO:0007052 |  | mitotic spindle organization |  | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the microtubule spindle during a mitotic cell cycle. | 
|  | GO:0006364 |  | rRNA processing |  | Any process involved in the conversion of a primary ribosomal RNA (rRNA) transcript into one or more mature rRNA molecules. | 
|  | GO:0042254 |  | ribosome biogenesis |  | A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of ribosome subunits; includes transport to the sites of protein synthesis. | 
  | cellular component | 
|---|
|  | GO:0005737 |  | cytoplasm |  | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. | 
|  | GO:0005856 |  | cytoskeleton |  | Any of the various filamentous elements that form the internal framework of cells, and typically remain after treatment of the cells with mild detergent to remove membrane constituents and soluble components of the cytoplasm. The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles. | 
|  | GO:0005730 |  | nucleolus |  | A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome. | 
|  | GO:0005654 |  | nucleoplasm |  | That part of the nuclear content other than the chromosomes or the nucleolus. | 
|  | GO:0005634 |  | nucleus |  | 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. | 
|  | GO:0005819 |  | spindle |  | The array of microtubules and associated molecules that forms between opposite poles of a eukaryotic cell during mitosis or meiosis and serves to move the duplicated chromosomes apart. | 
|  | GO:0000922 |  | spindle pole |  | 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. |
