| GO:0005575 | cellular_component | A location, relative to cellular compartments and structures, occupied by a macromolecular machine. There are three types of cellular components described in the gene ontology: (1) the cellular anatomical entity where a gene product carries out a molecular function (e.g., plasma membrane, cytoskeleton) or membrane-enclosed compartments (e.g., mitochondrion); (2) virion components, where viral proteins act, and (3) the stable macromolecular complexes of which gene product are parts (e.g., the clathrin complex). |
| GO:0005622 | intracellular anatomical structure | A component of a cell contained within (but not including) the plasma membrane. In eukaryotes it includes the nucleus and cytoplasm. |
| GO:0110165 | cellular anatomical structure | A part of a cellular organism consisting of a material entity with granularity above the level of a protein complex but below that of an anatomical system. Note that cellular organisms exclude viruses. |
| GO:0043226 | organelle | 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. |
| GO:0043229 | intracellular organelle | 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. |
| GO:0043228 | membraneless organelle | Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane. Includes ribosomes, the cytoskeleton and chromosomes. |
| GO:0043232 | intracellular membraneless organelle | 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. |
| GO:0000785 | chromatin | The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome. |
| GO:0005694 | chromosome | A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information. |
| GO:0000775 | chromosome, centromeric region | 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. |
| GO:0098687 | chromosomal region | Any subdivision of a chromosome along its length. |
| GO:0000792 | heterochromatin | A compact and highly condensed form of chromatin that is refractory to transcription. |
| GO:0005700 | polytene chromosome | A type of chromosome in a polyploid cell, formed when multiple copies of homologous chromosomes are aligned side by side to give a giant chromosome in which distinct chromosome bands are readily visible. |
| GO:0010369 | chromocenter | A region in which centric, heterochromatic portions from more than one chromosomes form a compact structure. |
| GO:0005701 | polytene chromosome chromocenter | A region at which the centric regions of polytene chromosomes are joined together. |
| GO:0005721 | pericentric heterochromatin | Heterochromatin that is located adjacent to the CENP-A rich centromere 'central core' and characterized by methylated H3 histone at lysine 9 (H3K9me2/H3K9me3). |
| GO:0005723 | alpha-heterochromatin | A small, compact region of heterochromatin located in the middle of the polytene chromosome chromocenter, which undergoes little or no replication during polytenization. |
