    The correct answer is helicase and nuclease.

    Nucleotide excision repair is a mechanism for DNA repair which removes DNA damage often induced by ultraviolet light (UV). The mechanism includes recognition of damage, dual incision, repair, and ligation.

    The step of incision occurs via enzyme which has helicase activity (unwind DNA and cut it). The same enzyme also has endonuclease activity (removal of a damage-containing DNA).
