Nucleotide Excision Repair (NER) est un système important de réparation de l’excision de l’ADN dans les cellules. It is not intended to provide medical, legal, or any other professional advice. In nucleotide excision repair, the repair machinery recognizes a wide array of distortions in the double helix caused by mismatched bases; in this form of repair, the entire distorted region is excised. Last Updated: May 26, 2017 . In base excision repair, DNA glycosylases specifically identify and remove the mismatched base. Enzymes recognize damage within DNA, probably by detecting an altered conformation of DNA, and then nick the strand on either side of the lesion, allowing a small single-stranded DNA to be excised.

If the balance of nature is left untouched, landscapes can change dramatically over time. Blood loss can be a significant complication. Friedberg, in Encyclopedia of Biological Chemistry (Second Edition), 2013. Examples include uracil DNA glycosylases, single-strand selective monofunctional uracil-DNA glycosylase (SMUG1), and thymine DNA glycosylase (TDG).
