CRISPR/Cas9 is a system found in bacteria and involved in immune defence. Bacteria use CRISPR/Cas9 to cut up the DNA of invading bacterial viruses that might otherwise kill them. Today we’ve adapted this molecular machinery for an entirely different purpose – to change any chosen letter(s) in an … See more In order to target our Cas9 scissors, we link them to an artificial guide that directs them to the matching segment of DNA. Remember, DNA comes in two strands, with one strand fitting alongside the other. We make a guide … See more Most experiments use mouse embryos or cells grown in petri dishes in artificial liquid designed to be like blood. Other researchers are modifying stem cells that may then be re-injected into patients to repopulate damaged … See more WebThe past decade has witnessed the discovery, engineering, and deployment of RNA-programmed genome editors across many applications.
