molecular function |
| GO:0003677 | | DNA binding | | Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). |
| GO:0003916 | | DNA topoisomerase activity | | Catalysis of the transient cleavage and passage of individual DNA strands or double helices through one another, resulting a topological transformation in double-stranded DNA. |
| GO:0003917 | | DNA topoisomerase type I activity | | Catalysis of a DNA topological transformation by transiently cleaving one DNA strand at a time to allow passage of another strand; changes the linking number by +1 per catalytic cycle. |
| GO:0003918 | | DNA topoisomerase type II (ATP-hydrolyzing) activity | | Catalysis of a DNA topological transformation by transiently cleaving a pair of complementary DNA strands to form a gate through which a second double-stranded DNA segment is passed, after which the severed strands in the first DNA segment are rejoined; product release is coupled to ATP binding and hydrolysis; changes the linking number in multiples of 2. |
| GO:0016853 | | isomerase activity | | Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5. |
biological process |
| GO:0006271 | | DNA strand elongation involved in DNA replication | | The process in which a DNA strand is synthesized from template DNA during replication by the action of polymerases, which add nucleotides to the 3' end of the nascent DNA strand. |
| GO:0006265 | | DNA topological change | | The process in which a transformation is induced in the topological structure of a double-stranded DNA helix, resulting in a change in linking number. |
| GO:0006333 | | chromatin assembly or disassembly | | The formation or destruction of chromatin structures. |
| GO:0006338 | | chromatin remodeling | | Dynamic structural changes to eukaryotic chromatin occurring throughout the cell division cycle. These changes range from the local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation. |
| GO:0000183 | | chromatin silencing at rDNA | | Repression of transcription of ribosomal DNA by altering the structure of chromatin. |
| GO:0007076 | | mitotic chromosome condensation | | The cell cycle process in which chromatin structure is compacted prior to and during mitosis in eukaryotic cells. |
| GO:0007097 | | nuclear migration | | The directed movement of the nucleus. |
| GO:0000019 | | regulation of mitotic recombination | | Any process that modulates the frequency, rate or extent of DNA recombination during mitosis. |
| GO:0006357 | | regulation of transcription from RNA polymerase II promoter | | Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter. |
| GO:0006368 | | transcription elongation from RNA polymerase II promoter | | The extension of an RNA molecule after transcription initiation and promoter clearance at an RNA polymerase II promoter by the addition of ribonucleotides catalyzed by RNA polymerase II. |
cellular component |
| GO:0005694 | | chromosome | | A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information. |
| GO:0005730 | | nucleolus | | 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. |
| GO:0005654 | | nucleoplasm | | That part of the nuclear content other than the chromosomes or the nucleolus. |
| GO:0005634 | | nucleus | | 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. |
| GO:0031298 | | replication fork protection complex | | A protein complex conserved in eukaryotes and associated with the replication fork; the complex stabilizes stalled replication forks and is thought to be involved in coordinating leading- and lagging-strand synthesis and in replication checkpoint signaling. |
