library_construction_protocol: Genomic DNA (gDNA) of cell pellets was isolated using a Quick-DNA Miniprep Plus kit (Zymo Research). PCR was performed on gDNA to construct Illumina sequencing libraries, each containing 5 μg gDNA, according to the Broad Institute protocol for PCR of sgRNAs for Illumina sequencing.
