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.
The Chemical Reactions and Pathways Including Anabolism and Catabolism by Which Living Organisms Transform Chemical Substances. Metabolic Processes Typically Transform Small Molecules But Also Include Macromolecular Processes Such As DNA Repair and Replication and Protein Synthesis and Degradation.
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.
Interacting Selectively and Non Covalently with a Transition Metal Ions; a Transition Metal Is an Element Whose Atom Has an Incomplete D Subshell of Extranuclear Electrons or Which Gives Rise to a Cation or Cations with an Incomplete D Subshell. Transition Metals Often Have More Than One Valency State. Biologically Relevant Transition Metals Include Vanadium Manganese Iron Copper Cobalt Nickel Molybdenum and Silver.
