    GO ID   Ontology GO Term Definition
    6281   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. 
    3677   DNA Binding  Any Molecular Function by Which a Gene Product Interacts Selectively and Non Covalently with DNA (deoxyribonucleic Acid). 
    3824   Catalytic Activity  Catalysis of a Biochemical Reaction At Physiological Temperatures. in Biologically Catalyzed Reactions the Reactants Are Known As Substrates and the Catalysts Are Naturally Occurring Macromolecular Substances Known As Enzymes. Enzymes Possess Specific Binding Sites For Substrates and Are Usually Composed Wholly or Largely of Protein But RNA That Has Catalytic Activity (ribozyme) Is Often Also Regarded As Enzymatic. 
    33699   DNA 5' Adenosine Monophosphate Hydrolase Activity  Catalysis of the Reaction: 5' AMP DNA + H2o = AMP + Dna; Nucleophilic Release of a Covalently Linked Adenylate Residue From a DNA Strand Leaving a 5' Phosphate Terminus.
