A DNA Repair Process in Which a Small Region of the Strand Surrounding the Damage Is Removed 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. Nucleotide Excision Repair Recognizes a Wide Range of Substrates Including Damage Caused by Uv Irradiation (pyrimidine Dimers and 6 4 Photoproducts) and Chemicals (intrastrand Cross Links and Bulky Adducts).
The 7 Subunit Core of Tfiih That Is a Part of Either the General Transcription Factor Holo Tfiih or the Nucleotide Excision Repair Factor 3 Complex. in S. Cerevisiae/humans the Complex Is Composed Of: Ssl2/xpb Tfb1/p62 Tfb2/p52 Ssl1/p44 Tfb4/p34 Tfb5/p8 and Rad3/xpd.
