Label Id Description
early recombination nodule GO_0005714 [An electron dense structure that is associated with meiotic chromosomes in leptotene or zygotene during meiosis I.]
late recombination nodule GO_0005715 [An electron dense structure that is associated with meiotic chromosomes in pachytene during meiosis I.]
GO_0005716 GO_0005716
GO_0005717 GO_0005717
GO_0005718 GO_0005718
GO_0005719 GO_0005719
GO_0005720 GO_0005720
pericentric heterochromatin GO_0005721 [Heterochromatin that is located adjacent to the CENP-A rich centromere 'central core' and characterized by methylated H3 histone at lysine 9 (H3K9me2/H3K9me3).]
beta-heterochromatin GO_0005722 [A diffusely banded region of heterochromatin located between euchromatin and alpha-heterochromatin in the polytene chromosome chromocenter; normally replicated during polytenization.]
alpha-heterochromatin GO_0005723 [A small, compact region of heterochromatin located in the middle of the polytene chromosome chromocenter, which undergoes little or no replication during polytenization.]
obsolete nuclear telomeric heterochromatin GO_0005724 [OBSOLETE. Heterochromatic regions of the chromosome found at the telomeres of a chromosome in the nucleus.]
intercalary heterochromatin GO_0005725 [Any of the regions of heterochromatin that form a reproducible set of dense bands scattered along the euchromatic arms in polytene chromosomes.]
perichromatin fibrils GO_0005726 [Structures of variable diameter visible in the nucleoplasm by electron microscopy, mainly observed near the border of condensed chromatin. The fibrils are enriched in RNA, and are believed to be sites of pre-mRNA splicing and polyadenylylation representing the in situ form of nascent transcripts.]
extrachromosomal circular DNA GO_0005727 [Circular DNA structures that are not part of a chromosome.]
extrachromosomal rDNA circle GO_0005728 [Circular DNA molecules encoding ribosomal RNA that are replicated independently of chromosomal replication. These molecules originate in the chromosome but are excised and circularized, often by intramolecular homologous recombination between direct tandem repeats.]
2-micrometer circle DNA GO_0005729 [A plasmid commonly found in Saccharomyces, inherited in a non-Mendelian manner and often present in 100-400 copies.]
nucleolus GO_0005730 [A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome.]
nucleolus organizer region GO_0005731 [A region of a chromosome where nucleoli form during interphase, and where genes encoding the largest rRNA precursor transcript are tandemly arrayed.]
obsolete small nucleolar RNA GO_0005733 [OBSOLETE. (Was not defined before being made obsolete).]
obsolete box C + D snoRNP protein GO_0005734 [OBSOLETE. (Was not defined before being made obsolete).]
