Abstract

When the DNA in cells is damaged by chemical or physical agents, such as ultraviolet light, the damage can lead to DNA mutations or even cell death. Cells use various DNA-repair proteins to fix any damage and to prevent damage-induced mutations and killing.

Keywords:

  • DNA repair;
  • mutations;
  • cell death;
  • excision repair;
  • reversal of damage
