The removal of the oligonucleotide that contains the DNA damage. The oligonucleotide is formed by dual incisions that flank the site of DNA damage [goid 718] [pmid 10583946] [evidence EXP]; The error-free repair of a double-strand break in DNA in which the broken DNA molecule is repaired using homologous sequences. A strand in the broken DNA searches for a homologous region in an intact chromosome to serve as the template for DNA synthesis. The restoration of two intact DNA molecules results in the exchange, reciprocal or nonreciprocal, of genetic material between the intact DNA molecule and the broken DNA molecule [goid 724] [pmid 14728600] [evidence IMP]; The endonucleolytic cleavage of the damaged strand of DNA 3' to the site of damage. The incision occurs at the junction of single-stranded DNA and double-stranded DNA that is formed when the DNA duplex is unwound. The incision precedes the incision formed 5' to the site of damage [goid 6295] [pmid 11790111] [evidence IMP]; The endonucleolytic cleavage of the damaged strand of DNA 5' to the site of damage. The incision occurs at the junction of single-stranded DNA and double-stranded DNA that is formed when the DNA duplex is unwound. The incision follows the incision formed 3' to the site of damage [goid 6296] [pmid 14728600] [evidence IMP]; The endonucleolytic cleavage of the damaged strand of DNA 5' to the site of damage. The incision occurs at the junction of single-stranded DNA and double-stranded DNA that is formed when the DNA duplex is unwound. The incision follows the incision formed 3' to the site of damage [goid 6296] [pmid 11790111] [evidence IMP]; Any process by which an organism or cell protects itself from ultraviolet radiation (UV), which may also result in resistance to repeated exposure to UV [goid 9650] [evidence IEA]; Any process that stops, prevents or reduces the frequency, rate or extent of a process that affects and monitors the activity of telomeric proteins and the length of telomeric DNA [goid 32205] [pmid 17055345] [evidence IMP]; The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway [goid 6281] [evidence IEA]; Any process by which an organism or cell protects itself from ultraviolet radiation (UV), which may also result in resistance to repeated exposure to UV [goid 9650] [evidence IEA]
