pyrimidine dimer repair by nucleotide-excision repair
pyrimidine dimer repair by nucleotide-excision repair
The repair of UV-induced T-T, C-T, and C-C dimers by the recognition and removal of the damaged DNA strand from the DNA helix as an oligonucleotide. The small gap left in the DNA helix is filled in by the sequential action of DNA polymerase and DNA ligase.
