Selective excision of the damaged section and use of the complementary strand to replace the excised portion is the most common method for repairing damage to DNA. This process is called nucleotide excision repair (NER) and involves the removal of the damaged section of DNA followed by the insertion of a new, undamaged section using the complementary strand as a template. This method is effective for repairing damage caused by exposure to UV light and certain chemicals.
