General Information

Term

double-strand break repair via single-strand annealing

ID (Ontology)

GO:0045002 (Gene Ontology)

Definition

Repair of a DSB made between two repeated sequences oriented in the same direction occurs primarily by the single strand annealing pathway. The ends of the break are processed by a 5' to 3' exonuclease, exposing complementary single-strand regions of the direct repeats that can anneal, resulting in a deletion of the unique DNA between the direct repeats.[ PubMed:11606529 ]
