1. A method for RNA-directed nuclease editing comprising the steps of:
designing and synthesizing a first linear vector backbone library comprising a coding sequence for a nuclease, a coding sequence for a first portion of a first antibiotic resistance gene fused to an N-terminus of a first intein, and first homology regions for inserting a first library of editing cassettes;
designing and synthesizing a second linear vector backbone library comprising a coding sequence for a nuclease, a coding sequence for a second portion of a first antibiotic resistance gene fused to an C-terminus of the first intein, and second homology regions for inserting a second library of editing cassettes;
designing and synthesizing the first library of editing cassettes, wherein each editing cassette comprises (i) a sequencing encoding a gRNA (ii) and a donor DNA, and wherein homology exists between the first library of editing cassettes and the first linear vector library;
designing and synthesizing the second library of editing cassettes, wherein each editing cassette comprises (i) a sequence encoding a gRNA and (ii) a donor DNA, and wherein homology exists between the second library of editing cassettes and the second linear vector library;
transforming cells with the first and second linear vector backbone libraries and first and second libraries of editing cassettes;
selecting for transformed cells by selecting for antibiotic resistance to the first antibiotic; and
providing conditions for RNA-directed nuclease editing in the cells to produce first edited cells.
