The deoxyribonucleic acid (DNA) damage response pathway is a surveillance network whereby lesions are eliminated from DNA. DNA damage response detects aberrant DNA and chromosomal structures and coordinates it in some manner with each of the other DNA transactions, including regulation of the cell cycle, DNA repair, replication and under some circumstances the triggering of programmed cell death. Many aspects of DNA damage signaling are highly conserved throughout evolution.
