    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. 
    6310   DNA Recombination  Any Process in Which a New Genotype Is Formed by Reassortment of Genes Resulting in Gene Combinations Different From Those That Were Present in the Parents. in Eukaryotes Genetic Recombination Can Occur by Chromosome Assortment Intrachromosomal Recombination or Nonreciprocal Interchromosomal Recombination. Intrachromosomal Recombination Occurs by Crossing Over. in Bacteria It May Occur by Genetic Transformation Conjugation Transduction or F Duction. 
    51103   DNA Ligation Involved in DNA Repair  The Re Formation of a Broken Phosphodiester Bond in the DNA Backbone Carried Out by DNA Ligase That Contributes to DNA Repair. 
    3677   DNA Binding  Any Molecular Function by Which a Gene Product Interacts Selectively and Non Covalently with DNA (deoxyribonucleic Acid). 
    3910   DNA ligase (ATP) activity  Catalysis of the Reaction: ATP + Deoxyribonucleotide(n) + Deoxyribonucleotide(m) = AMP + Diphosphate + Deoxyribonucleotide(n+m). 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator.
