1. A non-naturally occurring or engineered composition comprising: a Clustered Regularly Interspersed Short Palindromic Repeats (CRISPR)-CRISPR associated (Cas) (CRISPR-Cas) system chimeric RNA (chiRNA) polynucleotide sequence, wherein the polynucleotide sequence comprises
(a) a guide sequence of between 10 - 30 nucleotides in length, capable of hybridizing to a target sequence in a eukaryotic cell,
(b) a tracr mate sequence, and
(c) a tracrRNA sequence
wherein (a), (b) and (c) are arranged in a 5' to 3' orientation,
wherein when transcribed, the tracr mate sequence hybridizes to the tracrRNA sequence and the guide sequence directs sequence-specific binding of a CRISPR complex to the target sequence,
wherein the CRISPR complex comprises a Type II Cas9 protein complexed with (1) the guide sequence that is hybridized to the target sequence, and (2) the tracr mate sequence that is hybridized to the tracrRNA sequence,
wherein the tracrRNA sequence is 50 or more nucleotides in length.
