Descriptor reparación del ADN
Entry term(s) reparación por escisión de nucleótido
Scope note: Reconstrucción de una molécula de ADN con sus dos filamentos continuos, sin errores, a partir de una molécula que contiene regiones dañadas. Los principales mecanismos reparadores son: la reparación por escisión, mediante el cual las regiones defectuosas en un filamento son escindidas y resintetizadas merced a la información de los pares de bases complementarios de la cadena intacta; la reparación por fotorreactivación, en la que se eliminan los efectos letales o mutágenos de la luz ultravioleta; y la reparación mediante post-replicación, en la que no se reparan las lesiones primarias, pero los huecos en una hija duplicada son rellenados incorporando porciones de la otra hija duplicada (no dañada). Las reparaciones por escisión y por post-replicación también se denominan "reparaciones oscuras" puesto que no precisan luz para efectuarse.

Scope note: The reconstruction of a continuous two-stranded DNA molecule without mismatch from a molecule which contained damaged regions. The major repair mechanisms are excision repair, in which defective regions in one strand are excised and resynthesized using the complementary base pairing information in the intact strand; photoreactivation repair, in which the lethal and mutagenic effects of ultraviolet light are eliminated; and post-replication repair, in which the primary lesions are not repaired, but the gaps in one daughter duplex are filled in by incorporation of portions of the other (undamaged) daughter duplex. Excision repair and post-replication repair are sometimes referred to as "dark repair" because they do not require light.
