Genome editing.

Recent advances in genome editing technologies have redefined our ability to probe and precisely edit the human genome and epigenome in vitro and in vivo. More specifically, RNA-guided CRISPR/Cas systems have revolutionized the field due to their simplicity in design and adaptability across biological systems. This Collection highlights results in CRISPR/Cas technology that increase the efficiency of precision genome editing, and allow genetic manipulation in model systems traditionally intractable to site-directed gene modification.
