What Mechanisms Do Cells Use to Repair UV-Induced Damage?
Cells employ several mechanisms to repair UV-induced damage. One of the primary pathways is the nucleotide excision repair (NER) pathway, which recognizes and removes bulky DNA lesions such as thymine dimers. There is also the base excision repair (BER) pathway that corrects smaller, non-bulky lesions. Additionally, cells can activate apoptosis to remove severely damaged cells, preventing them from becoming cancerous.
