1. A composition comprising:
an activator-RNA comprising a duplex-forming segment comprising a nucleotide sequence capable of hybridizing with a targeter-RNA to form a DNA-targeting RNA that forms a complex with a Cas9 protein and guides the complex to a target sequence of a target DNA,
wherein the activator-RNA comprises one or more non-natural internucleoside linkages, one or more nucleic acid mimetics, one or more modified sugar moieties, one or more modified nucleobases, or any combination thereof.
