Genome Res. They illustrate the subtle, yet insidious, idea that some genes are inherently bad and contaminate the human gene pool; as such, people who carry them should not propagate and pass those genes on to their progeny so as to make those children either carriers or affected. WebAnswer (1 of 2): CRISPR/Cas9 is a powerful gene editing tools which may serve different purposes and can be applied in several way : * Knock-out : insertion of mutation ( indels ) Spatial and Temporal control of CRISPR-Cas9-mediated gene editing delivered via a light-triggered liposome system.
