GO:0008152 metabolic process The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
GO:0006338 chromatin remodeling Dynamic structural changes to eukaryotic chromatin occurring throughout the cell division cycle. These changes range from the local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation.
GO:0051276 chromosome organization 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.
GO:0071704 organic substance metabolic process The chemical reactions and pathways involving an organic substance, any molecular entity containing carbon.
GO:0006333 chromatin assembly or disassembly The formation or destruction of chromatin structures.
GO:0010468 regulation of gene expression Any process that modulates the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA (for protein-coding genes) and the translation of that mRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
GO:0016568 chromatin modification The alteration of DNA, protein, or sometimes RNA, in chromatin, which may result in changing the chromatin structure.
GO:0006325 chromatin organization Any process that results in the specification, formation or maintenance of the physical structure of eukaryotic chromatin.
GO:0040029 regulation of gene expression, epigenetic Any process that modulates the frequency, rate or extent of gene expression; the process is mitotically or meiotically heritable, or is stably self-propagated in the cytoplasm of a resting cell, and does not entail a change in DNA sequence.
GO:0009987 cellular process Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
GO:0016043 cellular component organization A process that results in the assembly, arrangement of constituent parts, or disassembly of a cellular component.
GO:0071840 cellular component organization or biogenesis A process that results in the biosynthesis of constituent macromolecules, assembly, arrangement of constituent parts, or disassembly of a cellular component.
GO:0008150 biological_process Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end.
GO:0006996 organelle organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an organelle within a cell. An organelle is an organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton. Excludes the plasma membrane.
GO:0043170 macromolecule metabolic process The chemical reactions and pathways involving macromolecules, any molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass.
GO:0065007 biological regulation Any process that modulates a measurable attribute of any biological process, quality or function.
GO:0060255 regulation of macromolecule metabolic process Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving macromolecules, any molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass.
GO:0050789 regulation of biological process Any process that modulates the frequency, rate or extent of a biological process. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule.
GO:0019222 regulation of metabolic process Any process that modulates the frequency, rate or extent of the chemical reactions and pathways within a cell or an organism.
GO:0043933 macromolecular complex subunit organization Any process in which macromolecules aggregate, disaggregate, or are modified, resulting in the formation, disassembly, or alteration of a macromolecular complex.
GO:0065003 macromolecular complex assembly The aggregation, arrangement and bonding together of a set of macromolecules to form a complex.
GO:0044085 cellular component biogenesis A process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of a cellular component. Includes biosynthesis of constituent macromolecules, and those macromolecular modifications that are involved in synthesis or assembly of the cellular component.
GO:0022607 cellular component assembly The aggregation, arrangement and bonding together of a cellular component.
GO:0010467 gene expression The process in which a gene's sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA (for protein-coding genes) and the translation of that mRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
GO:0071103 DNA conformation change A cellular process that results in a change in the spatial configuration of a DNA molecule. A conformation change can bend DNA, or alter the, twist, writhe, or linking number of a DNA molecule.
GO:0006323 DNA packaging Any process in which DNA and associated proteins are formed into a compact, orderly structure.
GO:0031497 chromatin assembly The assembly of DNA, histone proteins, other associated proteins, and sometimes RNA, into chromatin structure, beginning with the formation of the basic unit, the nucleosome, followed by organization of the nucleosomes into higher order structures, ultimately giving rise to a complex organization of specific domains within the nucleus.
GO:0007549 dosage compensation Compensating for the two-fold variation in X:autosome chromosome ratios between sexes by a global activation or inactivation of all, or most of, genes on one or both of the X chromosomes.
GO:0009048 dosage compensation by inactivation of X chromosome Compensating for the two-fold variation in X-chromosome:autosome ratios between sexes by a global inactivation of all, or most of, the genes on one of the X-chromosomes in the XX sex.
GO:0031507 heterochromatin assembly The assembly of chromatin into heterochromatin, a compact and highly condensed form that is often, but not always, transcriptionally silent.
