EOG84BDG1 GO:0005634 1/93 nucleus cellular_component "A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent." [GOC:go_curators] EOG84BDG1 GO:0005700 1/93 polytene chromosome cellular_component "A type of chromosome in a polyploid cell, formed when multiple copies of homologous chromosomes are aligned side by side to give a giant chromosome in which distinct chromosome bands are readily visible." [ISBN:0198506732] EOG84BDG1 GO:0010629 1/93 negative regulation of gene expression biological_process "Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA (for protein-coding genes) and the translation of that mRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form." [GOC:dph, GOC:tb] EOG84BDG1 GO:0016321 1/93 female meiosis chromosome segregation biological_process "The cell cycle process in which genetic material, in the form of chromosomes, is organized and then physically separated and apportioned to two or more sets during the meiotic cell cycle in a female." [GOC:ai] EOG84BDG1 GO:0005654 1/93 nucleoplasm cellular_component "That part of the nuclear content other than the chromosomes or the nucleolus." [GOC:ma, ISBN:0124325653] EOG84BDG1 GO:0007552 1/93 metamorphosis biological_process "A biological process in which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's form or structure. Examples include the change from tadpole to frog, and the change from larva to adult. An example of this is found in Drosophila melanogaster." [GOC:sensu, ISBN:0198506732, ISBN:0721662544] EOG84BDG1 GO:0000705 1/93 achiasmate meiosis I biological_process "The first division of meiosis in which homologous chromosomes are paired and segregated from each other, occurring in the constitutive absence of chiasmata."
