    6259   DNA Metabolic Process  Any Cellular Metabolic Process Involving Deoxyribonucleic Acid. This Is One of the Two Main Types of Nucleic Acid Consisting of a Long Unbranched Macromolecule Formed From One or More Commonly Two Strands of Linked Deoxyribonucleotides. 
    6265   DNA Topological Change  The Process in Which a Transformation Is Induced in the Topological Structure of a Double Stranded DNA Helix Resulting in a Change in Linking Number. 
    3677   DNA Binding  Any Molecular Function by Which a Gene Product Interacts Selectively and Non Covalently with DNA (deoxyribonucleic Acid). 
    3918   DNA topoisomerase type II (ATP-hydrolyzing) activity  Catalysis of a DNA Topological Transformation by Transiently Cleaving a Pair of Complementary DNA Strands to Form a Gate Through Which a Second Double Stranded DNA Segment Is Passed After Which the Severed Strands in the First DNA Segment Are Rejoined; Product Release Is Coupled to ATP Binding and Hydrolysis; Changes the Linking Number in Multiples of 2.
