    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. 
    6261   DNA Dependent DNA Replication  A DNA Replication Process That Uses Parental DNA As a Template For the DNA Dependent DNA Polymerases That Synthesize the New Strands. 
    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. 
    6284   Base Excision Repair  In Base Excision Repair an Altered Base Is Removed by a DNA Glycosylase Enzyme Followed by Excision of the Resulting Sugar Phosphate. the Small Gap Left in the DNA Helix Is Filled in by the Sequential Action of DNA Polymerase and DNA Ligase. 
    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. 
    5634   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. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    3677   DNA Binding  Any Molecular Function by Which a Gene Product Interacts Selectively and Non Covalently with DNA (deoxyribonucleic Acid). 
    3887   DNA Directed DNA Polymerase Activity  Catalysis of the Reaction: Deoxynucleoside Triphosphate + Dna(n) = Diphosphate + Dna(n+1); the Synthesis of DNA From Deoxyribonucleotide Triphosphates in the Presence of a DNA Template and a 3'hydroxyl Group. 
    16740   Transferase Activity  Catalysis of the Transfer of a Group E.g. a Methyl Group Glycosyl Group Acyl Group Phosphorus Containing or Other Groups From One Compound (generally Regarded As the Donor) to Another Compound (generally Regarded As the Acceptor). Transferase Is the Systematic Name For Any Enzyme of EC Class 2. 
    16779   Nucleotidyltransferase Activity  Catalysis of the Transfer of a Nucleotidyl Group to a Reactant. 
    16829   Lyase Activity  Catalysis of the Cleavage of C C C O C N and Other Bonds by Other Means Than by Hydrolysis or Oxidation or Conversely Adding a Group to a Double Bond. They Differ From Other Enzymes in That Two Substrates Are Involved in One Reaction Direction But Only One in the Other Direction. When Acting On the Single Substrate a Molecule Is Eliminated and This Generates Either a New Double Bond or a New Ring. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
