GO Term : GO:0040038 polar body extrusion after meiotic divisions GO

Namespace:  biological_process Obsolete:  false
description  The cell cycle process in which two small cells are generated, as byproducts destined to degenerate, as a result of the first and second meiotic divisions of a primary oocyte during its development to a mature ovum. One polar body is formed in the first division of meiosis and the other in the second division; at each division, the cytoplasm divides unequally, so that the polar body is of much smaller size than the developing oocyte. At the second division in which a polar body is formed, the polar body and the developing oocyte each contain a haploid set of chromosomes.

GO:0007049 cell cycle The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division.
GO:0051301 cell division The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells.
GO:0000910 cytokinesis The division of the cytoplasm and the plasma membrane of a cell and its partitioning into two daughter cells.
GO:0051321 meiotic cell cycle Progression through the phases of the meiotic cell cycle, in which canonically a cell replicates to produce four offspring with half the chromosomal content of the progenitor cell via two nuclear divisions.
GO:0061024 membrane organization A process which results in the assembly, arrangement of constituent parts, or disassembly of a membrane. A membrane is a double layer of lipid molecules that encloses all cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins.
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:0007126 meiotic nuclear division One of the two nuclear divisions that occur as part of the meiotic cell cycle.
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:0007143 female meiotic division A cell cycle process by which the cell nucleus divides as part of a meiotic cell cycle in the female germline.
GO:0044763 single-organism cellular process Any process that is carried out at the cellular level, occurring within a single organism.
GO:0044699 single-organism process A biological process that involves only one organism.
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:1902589 single-organism organelle organization An organelle organization which involves only one organism.
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:0000003 reproduction The production of new individuals that contain some portion of genetic material inherited from one or more parent organisms.
GO:0022402 cell cycle process The cellular process that ensures successive accurate and complete genome replication and chromosome segregation.
GO:0048285 organelle fission The creation of two or more organelles by division of one organelle.
GO:0000280 nuclear division The division of a cell nucleus into two nuclei, with DNA and other nuclear contents distributed between the daughter nuclei.
GO:1903046 meiotic cell cycle process A process that is part of the meiotic cell cycle.
GO:0022414 reproductive process A biological process that directly contributes to the process of producing new individuals by one or two organisms. The new individuals inherit some proportion of their genetic material from the parent or parents.
GO:0044702 single organism reproductive process A biological process that directly contributes to the process of producing new individuals, involving a single organism.
GO:0061640 cytoskeleton-dependent cytokinesis A cytokinesis that involves the function of a set of proteins that are part of the microfilament or microtubule cytoskeleton.
GO:0044802 single-organism membrane organization A process which results in the assembly, arrangement of constituent parts, or disassembly of a membrane, involving only one organism.
GO:0090148 membrane fission A process that is carried out at the cellular level which results in the separation of a single continuous membrane into two membranes.
GO:0033206 meiotic cytokinesis A cell cycle process that results in the division of the cytoplasm of a cell after meiosis, resulting in the separation of the original cell into two daughter cells.
GO:0040038 polar body extrusion after meiotic divisions The cell cycle process in which two small cells are generated, as byproducts destined to degenerate, as a result of the first and second meiotic divisions of a primary oocyte during its development to a mature ovum. One polar body is formed in the first division of meiosis and the other in the second division; at each division, the cytoplasm divides unequally, so that the polar body is of much smaller size than the developing oocyte.
