Embodiment approach 1

[0313] Embodiment 1. In some embodiments, a method of modifying a target nucleic acid is provided, comprising contacting the target nucleic acid with an Argonaute (Ago) protein and a single-stranded guide DNA at a temperature of about 10° C. to about 60° C., wherein the The Ago protein and the guide DNA form a complex that specifically recognizes a target locus in the target nucleic acid, and wherein the target locus comprises a sequence complementary to that of the guide DNA.

Embodiment approach 2

[0314] Embodiment 2: In other embodiments according to embodiment 1, the Ago protein cleaves the target locus.

Embodiment approach 3

[0315] Embodiment 3: In still other embodiments according to embodiment 2, wherein the target locus is double stranded DNA, the Ago protein induces a double strand break at the target locus.
