History of genome editing: From meganucleases to CRISPR

Abstract

CRISPR-mediated genome editing has undoubtedly revolutionized genetic engineering of animals. With the ability for virtually unlimited modification of almost any genome it is easy to forget which amazing discoveries paved the way for this ground-breaking technology. Here, we summarize the history of genome editing platforms, starting from enhanced integration of foreign DNA by meganuclease-mediated double-strand breaks to CRISPR/Cas9, the leading technology to date, and its re-engineered variants.
