GO Term : GO:0000744 karyogamy involved in conjugation with mutual genetic exchange GO

Namespace  biological_process Obsolete  false
Description  During sexual reproduction, the creation of a single nucleus from two nuclei as a result of fusing the nuclear envelopes that surround each nuclei. This takes place following the mutual exchange of one of the two nuclei produced by the mitosis that follows the second meiotic nuclear division. This occurs in ciliated protozoans such as Tetrahymena.

Identifier Name Description
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: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:0008150 biological_process A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence.
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:0016043 cellular component organization A process that results in the assembly, arrangement of constituent parts, or disassembly of a cellular component.
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:0006997 nucleus organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the nucleus.
GO:0019953 sexual reproduction A type of reproduction that combines the genetic material of two gametes (such as a sperm or egg cell or fungal spores). The gametes have an haploid genome (with a single set of chromosomes, the product of a meiotic division) and combines with one another to produce a zygote (diploid).
GO:0048284 organelle fusion The creation of a single organelle from two or more organelles.
GO:0000741 karyogamy The creation of a single nucleus from multiple nuclei as a result of fusing the lipid bilayers that surround each nuclei.
GO:0000744 karyogamy involved in conjugation with mutual genetic exchange During sexual reproduction, the creation of a single nucleus from two nuclei as a result of fusing the nuclear envelopes that surround each nuclei. This takes place following the mutual exchange of one of the two nuclei produced by the mitosis that follows the second meiotic nuclear division. This occurs in ciliated protozoans such as Tetrahymena.
GO:0000748 conjugation with mutual genetic exchange A conjugation process that results in the mutual exchange and union of only genetic information between compatible mating types. Conjugation without cellular fusion requires direct cellular contact between the organisms without plasma membrane fusion. The organisms involved in conjugation without cellular fusion separate after nuclear exchange.
