One of the distinct periods or stages into which the cell cycle is divided. Each phase is characterized by the occurrence of specific biochemical and morphological events. Note that this term should not be used for direct annotation. If you are trying to make an annotation to x phase, it is likely that the correct annotation is ‘regulation of x/y phase transition’ or to a process which occurs during the reported phase (i.e mitotic DNA replication for mitotic S-phase). To capture the phase when a specific location or process is observed, the phase term can be used in an annotation extension (PMID:24885854) applied to a cellular component term (with the relation exists_during) or a biological process term (with the relation happens_during).

Any biological process that results in permanent cessation of all vital functions of a cell. A cell should be considered dead when any one of the following molecular or morphological criteria is met: (1) the cell has lost the integrity of its plasma membrane; (2) the cell, including its nucleus, has undergone complete fragmentation into discrete bodies (frequently referred to as apoptotic bodies). The cell corpse (or its fragments) may be engulfed by an adjacent cell in vivo, but engulfment of whole cells should not be considered a strict criteria to define cell death as, under some circumstances, live engulfed cells can be released from phagosomes (see PMID:18045538). This term should not be used for direct annotation. The only exception should be when experimental data (e.g., staining with trypan blue or propidium iodide) show that cell death has occurred, but fail to provide details on death modality (accidental versus programmed). When information is provided on the cell death mechanism, annotations should be made to the appropriate descendant of ‘cell death’ (such as, but not limited to, GO:0097300 ‘programmed necrotic cell death’ or GO:0006915 ‘apoptotic process’). Also, if experimental data suggest that a gene product influences cell death indirectly, rather than being involved in the death process directly, consider annotating to a ‘regulation’ term.

The docking of a cytosolic centriole/basal body to the plasma membrane via the ciliary transition fibers. In some species this may happen via an intermediate step, by first docking to the ciliary vesicle via the ciliary transition fibers. The basal body-ciliary vesicle then relocates to the plasma membrane, followed by the ciliary vesicle fusing with the plasma membrane, effectively attaching the basal body to the plasma membrane. Basal bodies in jawed vertebrates appear to first attach to a ciliary vesicle. It is unclear how specific this is to jawed vertebrates or if other organisms also employ this sequence. Some species like Giardia intestinalis do not relocate their basal bodies to the plasma membrane, but have their axonemes extend through the cytosol to then protrude out of the cell to form flagella.
The process in which the ciliary body generated and organized. The ciliary body is the circumferential tissue inside the eye composed of the ciliary muscle and ciliary processes.
The portion of the plasma membrane surrounding a cilium. Note that cilia and eukaryotic flagella are deemed to be equivalent.
All of the contents of a cilium, excluding the plasma membrane surrounding the cilium. Note that we deem cilium and microtubule-based flagellum to be equivalent. Also, researchers consider the composition of both the plasm and the membrane of the cilium to be detectably different from that in the non-ciliary cytosol and plasma membrane (e.g. in terms of calcium ion concentration, membrane lipid composition, and more). For this reason, the term “ciliary plasm” is not linked to “cytoplasm”.
A region of the cilium between the basal body and proximal segment that is characterized by Y-shaped assemblages that connect axonemal microtubules to the ciliary membrane. The ciliary transition zone appears to function as a gate that controls ciliary membrane composition and separates the cytosol from the ciliary plasm. Depending on the species, this region may have a distinct geometrically shaped electron-dense structure within the axonemal lumen visible in electron microscopy images; most animals don’t display this inner structure. The axoneme extends through the ciliary transition zone, but only consists of the outer doublets. The central pair, axonemal spokes, and dynein complexes are not found in this part of the ciliary shaft. Note that the connecting cilium of the photoreceptor cells is thought to be equivalent to the transition zone.
The aggregation, arrangement and bonding together of a set of components to form a ciliary transition zone.
A specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface and of some cytoplasmic parts. Each cilium is largely bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored to a basal body. Note that we deem cilium and microtubule-based flagellum to be equivalent. In most eukaryotic species, intracellular sub-components of the cilium, such as the ciliary base and rootlet, are located near the plasma membrane. In Diplomonads such as Giardia, instead, the same ciliary parts are located further intracellularly. Also, ‘cilium’ may be used when axonemal structure and/or motility are unknown, or when axonemal structure is unusual. For all other cases, please refer to children of ‘cilium’. Finally, note that any role of ciliary proteins in sensory events should be captured by annotating to relevant biological process terms.
The assembly of a cilium, a specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface. Each cilium is bounded by an extrusion of the cytoplasmic membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole.

The process whose specific outcome is the progression of the midbrain over time, from its formation to the mature structure. The midbrain is the middle division of the three primary divisions of the developing chordate brain or the corresponding part of the adult brain (in vertebrates, includes a ventral part containing the cerebral peduncles and a dorsal tectum containing the corpora quadrigemina and that surrounds the aqueduct of Sylvius connecting the third and fourth ventricles).
The developmental process by which a midbrain is generated and organized.
The process whose specific outcome is the progression of the midbrain-hindbrain boundary over time, from its formation to the mature structure. The midbrain-hindbrain domain of the embryonic brain is comprised of the mesencephalic vesicle and the first rhombencephalic vesicle at early somitogenesis stages.
The regionalization process that gives rise to the midbrain-hindbrain boundary. The midbrain-hindbrain domain of the embryonic brain is comprised of the mesencephalic vesicle and the first rhombencephalic vesicle at early somitogenesis stages. An organizing center at the boundary patterns the midbrain and hindbrain primordia of the neural plate.
The process in which the anatomical structure of the midbrain-hindbrain boundary is generated and organized. The midbrain-hindbrain domain of the embryonic brain is comprised of the mesencephalic vesicle and the first rhombencephalic vesicle at early somitogenesis stages. An organizing center at the boundary patterns the midbrain and hindbrain primordia of the neural plate.
Progression through the phases of the mitotic cell cycle, the most common eukaryotic cell cycle, which canonically comprises four successive phases called G1, S, G2, and M and includes replication of the genome and the subsequent segregation of chromosomes into daughter cells. In some variant cell cycles nuclear replication or nuclear division may not be followed by cell division, or G1 and G2 phases may be absent. Note that this term should not be confused with ‘GO:0140014 ; mitotic nuclear division’. ‘GO:0000278 ; mitotic cell cycle represents the entire mitotic cell cycle, while ‘GO:0140014 ; mitotic nuclear division’ specifically represents the actual nuclear division step of the mitotic cell cycle.
One of the distinct periods or stages into which the mitotic cell cycle is divided. Each phase is characterized by the occurrence of specific biochemical and morphological events. This term should not be used for direct annotation. If you are trying to make an annotation to x phase, it is likely that the correct annotation should be to ‘regulation of x/y phase transition’ or to a process which occurs during the reported phase (e.g. mitotic DNA replication for mitotic S-phase). To capture the phase when a specific location or process is observed, the phase term can be used in an annotation extension (PMID:24885854) applied to a cellular component term (with the relation exists_during) or a biological process term (with the relation happens_during).
A process that is part of the mitotic cell cycle.
The eukaryotic cell cycle in which a cell is duplicated without changing ploidy, occurring in the embryo.
The cell cycle process in which chromatin structure is compacted prior to and during mitosis in eukaryotic cells.
The cell cycle phase following cytokinesis which begins with G1 phase, proceeds through S phase and G2 phase and ends when mitotic prophase begins. During interphase the cell readies itself for mitosis and the replication of its DNA occurs. Note that this term should not be used for direct annotation. If you are trying to make an annotation to x phase, it is likely that the correct annotation is ‘regulation of x/y phase transition’ or to a process which occurs during the reported phase (i.e mitotic DNA replication for mitotic S-phase). To capture the phase when a specific location or process is observed, the phase term can be used in an annotation extension (PMID:24885854) applied to a cellular component term (with the relation exists_during) or a biological process term (with the relation happens_during).
A cell cycle phase during which nuclear division occurs, and which is comprises the phases: prophase, metaphase, anaphase and telophase and occurs as part of a mitotic cell cycle. Note that this term should not be used for direct annotation. If you are trying to make an annotation to x phase, it is likely that the correct annotation is ‘regulation of x/y phase transition’ or to a process which occurs during the reported phase (i.e mitotic DNA replication for mitotic S-phase). To capture the phase when a specific location or process is observed, the phase term can be used in an annotation extension (PMID:24885854) applied to a cellular component term (with the relation exists_during) or a biological process term (with the relation happens_during).
A mitotic cell cycle process comprising the steps by which the nucleus of a eukaryotic cell divides; the process involves condensation of chromosomal DNA into a highly compacted form. Canonically, mitosis produces two daughter nuclei whose chromosome complement is identical to that of the mother cell.
The mitotic cell cycle process in which the controlled partial or complete breakdown of the nuclear membranes during occurs during mitosis.
A mitotic cell cycle process which results in the assembly, arrangement, or disassembly of the nuclear inner or outer membrane during mitosis. This process only occurs in organisms which undergo ‘closed mitosis’ without nuclear breakdown.
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.
Any process that modulates the frequency or amplitude of synaptic transmission, the process of communication from a neuron to a target (neuron, muscle, or secretory cell) across a synapse. Amplitude, in this case, refers to the change in postsynaptic membrane potential due to a single instance of synaptic transmission.
A molecular function regulator regulates the activity of its target via non-covalent binding that does not result in covalent modification to the target. Examples of molecular function regulators include regulatory subunits of multimeric enzymes and channels. Mechanisms of regulation include allosteric changes in the target and competitive inhibition.
A compound molecular function in which an effector function is controlled by one or more regulatory components.
A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs. These actions are described from two distinct but related perspectives: (1) biochemical activity, and (2) role as a component in a larger system/process. Note that, in addition to forming the root of the molecular function ontology, this term is recommended for use for the annotation of gene products whose molecular function is unknown. When this term is used for annotation, it indicates that no information was available about the molecular function of the gene product annotated as of the date the annotation was made; the evidence code ‘no data’ (ND), is used to indicate this. Despite its name, this is not a type of ‘function’ in the sense typically defined by upper ontologies such as Basic Formal Ontology (BFO). It is instead a BFO:process carried out by a single gene product or complex.
The directed movement of monoamines, organic compounds that contain one amino group that is connected to an aromatic ring by an ethylene group (-CH2-CH2-), into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
The directed movement of monocarboxylic acids into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
The process in which a relatively unspecialized cell acquires the specialized features of a mononuclear cell.
The expansion of a mononuclear cell population by cell division. A mononuclear cell is a leukocyte with a single non-segmented nucleus in the mature form.
The process in which the anatomical structures of a branched epithelium are generated and organized.
