In 2015, 3 scientists were awarded the Nobel Prize in Chemistry for their work detailing the molecular mechanisms that cells use to repair damaged DNA.1
Numerous repair pathways are activated in response to different types of damage, regulated and coordinated by the broader DNA damage response (DDR) network.

Maintaining Genomic Integrity
Cells are constantly under attack from a wide variety of potentially DNA-damaging assailants both within the organism and in the surrounding environment. DNA can be damaged by, among other things, exposure to ultraviolet light, ionizing radiation, toxic chemicals, reactive oxygen species, mechanical stress, and replication errors.
