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:0032508
|
DNA duplex unwinding
|
The process in which interchain hydrogen bonds between two strands of DNA are broken or 'melted', generating a region of unpaired single strands. |
GO:0016043
|
cellular component organization
|
A process that results in the assembly, arrangement of constituent parts, or disassembly of a cellular component. |
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: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: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:0032392
|
DNA geometric change
|
The process in which a transformation is induced in the geometry of a DNA double helix, resulting in a change in twist, writhe, or both, but with no change in linking number. Includes the unwinding of double-stranded DNA by helicases. |
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. |
