JONATHAN LATHAM – God’s Red Pencil? CRISPR and The Three Myths of Precise Genome Editing

For the benefit of those parts of the world where public acceptance of biotechnology is incomplete, a public relations blitz is at full tilt. It concerns an emerging set of methods for altering the DNA of living organisms. “Easy DNA Editing Will Remake the World. Buckle Up; “We Have the Technology to Destroy All Zika Mosquitoes“; and “CRISPR: gene editing is just the beginning”. (CRISPR is short for CRISPR/cas9, which is short for Clustered Regularly-Interspaced Short Palindromic Repeats/CRISPR associated protein 9; Jinek et al., 2012. It is a combination of a guide RNA and a protein that can cut DNA.)

The hubris is alarming; but the more subtle element of the propaganda campaign is the biggest and most dangerous improbability of them all: that CRISPR and related technologies are “genome editing” (Fichtner et al., 2014). That is, they are capable of creating precise, accurate and specific alterations to DNA.
