Label	Id	Description
mitotic sister chromatid cohesion	GO_0007064	[The cell cycle process in which the sister chromatids of a replicated chromosome are joined along the entire length of the chromosome, from their formation in S phase through metaphase during a mitotic cell cycle. This cohesion cycle is critical for high fidelity chromosome transmission.]
establishment of meiotic sister chromatid cohesion	GO_0034089	[The process in which the sister chromatids of a replicated chromosome become joined along the entire length of the chromosome during S phase during a meiotic cell cycle.]
establishment of sister chromatid cohesion	GO_0034085	[The process in which the sister chromatids of a replicated chromosome become associated with each other during S phase.]
type II polyketide synthase complex	GO_0034082	[A polyketide synthase complex that consists of several different polypeptide chains, each of which catalyzes a single reaction.]
polyketide synthase complex	GO_0034081	[A protein complex that carries out enzymatic reactions involved in the biosynthesis of polyketides, any of a diverse group of natural products synthesized via linear poly-beta-ketones.]
double-strand break repair via classical nonhomologous end joining	GO_0097680	[An instance of double-strand break repair via nonhomologous end joining that requires a number of factors important for V(D)J recombination, including the KU70/80 heterodimer (KU), XRCC4, ligase IV, and DNA-PKcs in mammals. It does not produce translocations (as opposed to the alternative nonhomologous end joining).]
double-strand break repair via nonhomologous end joining	GO_0006303	[The repair of a double-strand break in DNA in which the two broken ends are rejoined with little or no sequence complementarity. Information at the DNA ends may be lost due to the modification of broken DNA ends. This term covers instances of separate pathways, called classical (or canonical) and alternative nonhomologous end joining (C-NHEJ and A-NHEJ). These in turn may further branch into sub-pathways, but evidence is still unclear.]
type III polyketide synthase complex	GO_0034083	[A polyketide synthase complex that consists of two identical ketosynthase polypeptides.]
pyrimidine dimer DNA N-glycosylase activity	GO_0000704	[Catalysis of the removal of pyrimidine dimers by removing the 5' pyrimidine of the dimer by cleaving the N-C1' glycosidic bond between the 5' pyrimidine of the dimer and the deoxyribose sugar. The reaction releases the 5' pyrimidine of the dimer and leaves an apurinic (AP) site. The reaction involves the formation of a covalent enzyme substrate intermediate. Release of the enzyme and free base by a beta-elimination or a beta, gamma-elimination mechanism results in the cleavage of the DNA backbone 3' of the apyrimidinic (AP) site.]
double-strand break repair via alternative nonhomologous end joining	GO_0097681	[An instance of double-strand break repair via nonhomologous end joining that is independent of factors important for V(D)J recombination (as opposed to classical nonhomologous end joining). It often results in a deletion with microhomology (i.e. 5-25bp homology) at the repair junction. Among different subclasses of nonhomologous end joining (NHEJ), alternative NHEJ appears to play a significant role in the etiology of mutations that arise during cancer development and treatment.]
CENP-A containing nucleosome assembly	GO_0034080	[The formation of nucleosomes containing the histone H3 variant CENP-A to form centromeric chromatin. This specialised chromatin occurs at centromeric region in point centromeres, and the central core in modular centromeres.]
chromatin remodeling at centromere	GO_0031055	[Dynamic structural changes in centromeric DNA.]
DNA replication-independent nucleosome assembly	GO_0006336	[The formation of nucleosomes outside the context of DNA replication.]
histone exchange	GO_0043486	[The replacement, within chromatin, of resident histones or histone subunits with alternative, sometimes variant, histones or subunits.]
protein localization to CENP-A containing chromatin	GO_0061644	[Any process in which a protein is transported to, or maintained at, CENP-A containing chromatin.]
CENP-A containing chromatin organization	GO_0061641	[Any process that results in the specification, formation or maintenance of the physical structure of CENP-A containing chromatin.]
achiasmate meiosis I	GO_0000705	[The first division of meiosis in which homologous chromosomes are paired and segregated from each other, occurring in the constitutive absence of chiasmata.]
intracellular phosphatidylinositol-3,5-bisphosphate-sensitive cation channel activity	GO_0097682	[Enables the transmembrane transfer of cations by a channel that opens when phosphatidylinositol-3,5-bisphosphate has been bound by the channel complex or one of its constituent parts.]
oxidized base lesion DNA N-glycosylase activity	GO_0000702	[Catalysis of the removal of oxidized bases by cleaving the N-C1' glycosidic bond between the target damaged DNA base and the deoxyribose sugar. The reaction releases a free base and leaves an apurinic/apyrimidinic (AP) site.]
dinoflagellate apex	GO_0097683	[The anterior most point of a dinoflagellate epicone.]
