GO:0003676,MF,"nucleic acid binding","Interacting selectively and non-covalently with any nucleic acid.",IEA
GO:0005634,CC,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.",IEA
GO:0006259,BP,"DNA metabolic process","Any cellular metabolic process involving deoxyribonucleic acid. This is one of the two main types of nucleic acid, consisting of a long, unbranched macromolecule formed from one, or more commonly, two, strands of linked deoxyribonucleotides.",IBA
GO:0006281,BP,"DNA repair","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.",IEA
GO:0008296,MF,"3'-5'-exodeoxyribonuclease activity","Catalysis of the sequential cleavage of mononucleotides from a free 3' terminus of a DNA molecule.",IBA
GO:0008853,MF,"exodeoxyribonuclease III activity","Catalysis of the degradation of double-stranded DNA. It acts progressively in a 3' to 5' direction, releasing 5'-phosphomononucleotides.",IEA
