GO:0000775 | chromosome, centromeric region | cellular_component | The region of a chromosome that includes the centromeric DNA and associated proteins. In monocentric chromosomes, this region corresponds to a single area of the chromosome, whereas in holocentric chromosomes, it is evenly distributed along the chromosome. [GOC:cjm, GOC:elh, GOC:kmv, GOC:pr] |
GO:0007080 | mitotic metaphase plate congression | biological_process | The cell cycle process in which chromosomes are aligned at the metaphase plate, a plane halfway between the poles of the mitotic spindle, during mitosis. [GOC:mah, ISBN:0815316194] |
GO:0005730 | nucleolus | cellular_component | 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. [ISBN:0198506732] |
GO:0051276 | chromosome organization | biological_process | A process that is carried out at the cellular level that results in the assembly, arrangement of constituent parts, or disassembly of chromosomes, structures composed of a very long molecule of DNA and associated proteins that carries hereditary information. This term covers covalent modifications at the molecular level as well as spatial relationships among the major components of a chromosome. [GOC:ai, GOC:dph, GOC:jl, GOC:mah] |
GO:0030496 | midbody | cellular_component | A thin cytoplasmic bridge formed between daughter cells at the end of cytokinesis. The midbody forms where the contractile ring constricts, and may persist for some time before finally breaking to complete cytokinesis. [ISBN:0815316194] |
GO:0110165 | cellular anatomical entity | cellular_component | A part of a cellular organism that is either an immaterial entity or a material entity with granularity above the level of a protein complex but below that of an anatomical system. Or, a substance produced by a cellular organism with granularity above the level of a protein complex. [GOC:kmv] |
GO:0005829 | cytosol | cellular_component | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl] |
GO:0032991 | protein-containing complex | cellular_component | A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together. [GOC:dos, GOC:mah] |
GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
GO:0043228 | non-membrane-bounded organelle | cellular_component | Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane. Includes ribosomes, the cytoskeleton and chromosomes. [GOC:go_curators] |
GO:0005654 | nucleoplasm | cellular_component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |
GO:0005875 | microtubule associated complex | cellular_component | Any multimeric complex connected to a microtubule. [GOC:jl] |
GO:0015630 | microtubule cytoskeleton | cellular_component | The part of the cytoskeleton (the internal framework of a cell) composed of microtubules and associated proteins. [GOC:jl, ISBN:0395825172] |
GO:0051233 | spindle midzone | cellular_component | The area in the center of the spindle where the spindle microtubules from opposite poles overlap. [GOC:ai, PMID:15296749] |
GO:0043226 | organelle | cellular_component | Organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, and prokaryotic structures such as anammoxosomes and pirellulosomes. Excludes the plasma membrane. [GOC:go_curators] |
GO:0043229 | intracellular organelle | cellular_component | Organized structure of distinctive morphology and function, occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton. Excludes the plasma membrane. [GOC:go_curators] |
GO:0043232 | intracellular non-membrane-bounded organelle | cellular_component | Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane and occurring within the cell. Includes ribosomes, the cytoskeleton and chromosomes. [GOC:go_curators] |
GO:0000070 | mitotic sister chromatid segregation | biological_process | The cell cycle process in which replicated homologous chromosomes are organized and then physically separated and apportioned to two sets during the mitotic cell cycle. Each replicated chromosome, composed of two sister chromatids, aligns at the cell equator, paired with its homologous partner. One homolog of each morphologic type goes into each of the resulting chromosome sets. [GOC:ai, GOC:jl] |
