CRISPR Cas9 explained. CRISPR (clustered regularly interspaced short palindromic repeats) are segments of prokaryotic DNA containing short repetitions of base sequences. is an RNA-guided gene-editing platform that makes use of a bacterially derived protein (Cas9) and a synthetic guide RNA to introduce a double strand break at a specific location within the genome.
Cas9 is an enzyme that snips DNA, and CRISPR is a collection of DNA sequences that tells Cas9 exactly where to snip.
In this engaging article, meet Markita Landry, Assistant Professor of Chemical and Biomolecular Engineering, who runs the Landry Lab at UC Berkeley. Her lab works on developing nanomaterials to assist in the delivery of CRISPR-Cas9 systems in plants.
According to a newly published study in Nature, CasX is a potent and efficient gene editor in both bacteria and human cells. Its design is similar to Cas9 and its well-studied cousin, Cas12, but is different enough that it appears to have evolved in bacteria independently of the other Cas proteins. It can cut double-stranded DNA like Cas9, can bind to DNA to regulate genes, and it can be targeted to specific DNA sequences like other Cas proteins.
A breakthrough in genetic technology has given humans more power than ever to change nature. It could help eliminate hunger and disease; it could also lead to the sort of dystopia we used to only read about in sci-fi novels. 
Jennifer Doudna was awarded the Pearl Meister Greengard Prize in October 2018, established by Nobel Laureate Paul Greengard and his wife, the artist Ursula von Rydingsvard, to give recognition to women scientists. The New York Review spoke with her before the award ceremony. “That there even is a prize like this one,” Doudna said, “is a sign that people are really beginning to value the contributions of women to science.” 
Jennifer Doudna, a pioneer of the revolutionary genome-editing technology, reflects on how 2015 became the most intense year of her career — and what she's learned.

The University of California announced today that the U.S. Patent and Trademark Office has granted U.S. Patent Number 10,113,167, covering unique RNA guides that, when combined with the Cas9 protein, are effective at homing in on and editing genes. These RNA/protein combinations act like precision-targeted gene-editing scissors.
