1. A method for cleaving, editing, or modifying at least one sequence adjacent to a Protospacer Adjacent Motif (PAM) in a eukaryotic cell, comprising:
- delivering a non-naturally occurring or engineered single eukaryotic expression vector to the eukaryotic cell,wherein the expression vector comprises;
a) at least one nucleotide sequence encoding at least one chimeric construct comprising a tracr sequence comprising 30 or more nucleotides in length, andb) at least one nucleotide sequence encoding at least one Cas9,wherein;
components a) and b) are each operably linked to a regulatory element for transcription thereof in the eukaryotic cell and the expression vector includes at least one regulatory element therefor,the chimeric construct is designed to form with Cas9 a complex,the chimeric construct comprise(s) guide(s) designed to hybridize with the target sequence(s),the chimeric construct and Cas9 do not naturally occur together, andthe complex comprising the chimeric construct and Cas9 does not naturally occur, whereby there is cleaving, editing, or modifying of the target sequence.

Abstract
The invention provides for systems, methods, and compositions for manipulation of sequences and/or activities of target sequences. Provided are vectors and vector systems, some of which encode one or more components of a CRISPR complex, as well as methods for the design and use of such vectors. Also provided are methods of directing CRISPR complex formation in eukaryotic cells and methods for selecting specific cells by introducing precise mutations utilizing the CRISPR/CAS system.
