    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. 
    6270   DNA Replication Initiation  The Process in Which DNA Dependent DNA Replication Is Started; This Involves the Separation of a Stretch of the DNA Double Helix the Recruitment of DNA Polymerases and the Initiation of Polymerase Action. 
    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. 
    3676   Nucleic Acid Binding  Interacting Selectively and Non Covalently with Any Nucleic Acid. 
    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. 
    8408   3' 5' Exonuclease Activity  Catalysis of the Hydrolysis of Ester Linkages Within Nucleic Acids by Removing Nucleotide Residues From the 3' End.
