    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. 
    6298   Mismatch Repair  A System For the Correction of Errors in Which an Incorrect Base Which Cannot Form Hydrogen Bonds with the Corresponding Base in the Parent Strand Is Incorporated Into the Daughter Strand. the Mismatch Repair System Promotes Genomic Fidelity by Repairing Base Base Mismatches Insertion Deletion Loops and Heterologies Generated During DNA Replication and Recombination. 
    16798   Hydrolase Activity Acting On Glycosyl Bonds  Catalysis of the Hydrolysis of Any Glycosyl Bond. 
    16799   Hydrolase Activity Hydrolyzing N Glycosyl Compounds  Catalysis of the Hydrolysis of Any N Glycosyl Bond. 
    30983   Mismatched DNA Binding  Interacting Selectively and Non Covalently with Double Stranded DNA Containing One or More Mismatches.
