    GO ID   Ontology GO Term Definition
    6260   DNA Replication  The Cellular Metabolic Process in Which a Cell Duplicates One or More Molecules of Dna. DNA Replication Begins When Specific Sequences Known As Origins of Replication Are Recognized and Bound by Initiation Proteins and Ends When the Original DNA Molecule Has Been Completely Duplicated and the Copies Topologically Separated. the Unit of Replication Usually Corresponds to the Genome of the Cell an Organelle or a Virus. the Template For Replication Can Either Be an Existing DNA Molecule or Rna. 
    6266   DNA Ligation  The Re Formation of a Broken Phosphodiester Bond in the DNA Backbone Carried Out by DNA Ligase. 
    6273   Lagging Strand Elongation  The Synthesis of DNA From a Template Strand in a Net 3' to 5' Direction. Lagging Strand DNA Elongation Proceeds by Discontinuous Synthesis of Short Stretches of DNA Known As Okazaki Fragments From RNA Primers; These Fragments Are Then Joined by DNA Ligase. Although Each Segment of Nascent DNA Is Synthesized in the 5' to 3' Direction the Overall Direction of Lagging Strand Synthesis Is 3' to 5' Mirroring the Progress of the Replication Fork. 
    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. 
    6289   Nucleotide Excision Repair  A DNA Repair Process in Which a Small Region of the Strand Surrounding the Damage Is Removed From the DNA Helix As an Oligonucleotide. the Small Gap Left in the DNA Helix Is Filled in by the Sequential Action of DNA Polymerase and DNA Ligase. Nucleotide Excision Repair Recognizes a Wide Range of Substrates Including Damage Caused by Uv Irradiation (pyrimidine Dimers and 6 4 Photoproducts) and Chemicals (intrastrand Cross Links and Bulky Adducts). 
    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. 
    6974   Cellular Response to DNA Damage Stimulus  Any Process That Results in a Change in State or Activity of a Cell (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of a Stimulus Indicating Damage to Its DNA From Environmental Insults or Errors During Metabolism. 
    7049   Cell Cycle  The Progression of Biochemical and Morphological Phases and Events That Occur in a Cell During Successive Cell Replication or Nuclear Replication Events. Canonically the Cell Cycle Comprises the Replication and Segregation of Genetic Material Followed by the Division of the Cell But in Endocycles or Syncytial Cells Nuclear Replication or Nuclear Division May Not Be Followed by Cell Division. 
    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. 
    51301   Cell Division  The Process Resulting in Division and Partitioning of Components of a Cell to Form More Cells; May or May Not Be Accompanied by the Physical Separation of a Cell Into Distinct Individually Membrane Bounded Daughter Cells. 
    71897   DNA Biosynthetic Process  The Cellular DNA Metabolic Process Resulting in the Formation of DNA Deoxyribonucleic Acid One of the Two Main Types of Nucleic Acid Consisting of a Long Unbranched Macromolecule Formed From One or Two Strands of Linked Deoxyribonucleotides the 3' Phosphate Group of Each Constituent Deoxyribonucleotide Being Joined in 3' 5' Phosphodiester Linkage to the 5' Hydroxyl Group of the Deoxyribose Moiety of the Next One. 
    5694   Chromosome  A Structure Composed of a Very Long Molecule of DNA and Associated Proteins (e.g. Histones) That Carries Hereditary Information. 
    166   Nucleotide Binding  Interacting Selectively and Non Covalently with a Nucleotide Any Compound Consisting of a Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Ribose or Deoxyribose. 
    3677   DNA Binding  Any Molecular Function by Which a Gene Product Interacts Selectively and Non Covalently with DNA (deoxyribonucleic Acid). 
    3909   DNA Ligase Activity  Catalysis of the Formation of a Phosphodiester Bond Between the 3' Hydroxyl Group At the End of One DNA Chain and the 5' Phosphate Group At the End of Another. This Reaction Requires an Energy Source Such As ATP or Nad+. 
    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. 
    16874   Ligase Activity  Catalysis of the Joining of Two Substances or Two Groups Within a Single Molecule with the Concomitant Hydrolysis of the Diphosphate Bond in ATP or a Similar Triphosphate. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
