There is pairing of microhomology regions followed by recruitment of flap structure-specific endonuclease 1 (FEN1) to remove overhanging flaps.
Hai un emparellamento de rexións de microhomoloxía seguida do recrutamento da endonuclease FEN1 (flap structure-specific endonuclease 1) para que elimine as solapas que sobresaen.
