EOG84TRNP GO:0006281 8/45 DNA repair biological_process "The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway." [PMID:11563486] EOG84TRNP GO:0000723 8/45 telomere maintenance biological_process "Any process that contributes to the maintenance of proper telomeric length and structure by affecting and monitoring the activity of telomeric proteins and the length of telomeric DNA. These processes includes those that shorten and lengthen the telomeric DNA sequences." [GOC:elh, PMID:11092831] EOG84TRNP GO:0003678 8/45 DNA helicase activity molecular_function "Catalysis of the reaction: NTP + H2O = NDP + phosphate, to drive the unwinding of a DNA helix."

[ISBN:0198506732] EOG84TRNP GO:0003677 1/45 DNA binding molecular_function "Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid)."

[GOC:elh] EOG84TRNP GO:0005634 1/45 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] EOG84TRNP GO:0006334 1/45 nucleosome assembly biological_process "The aggregation, arrangement and bonding together of a nucleosome, the beadlike structural units of eukaryotic chromatin composed of histones and DNA."
