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.
The Rockefeller University has announced that Jennifer Doudna will receive this year's Pearl Meister Greengard Prize, a major international accolade honoring outstanding women scientists.

The Court of Appeals today concluded that the use of CRISPR-Cas9 in plant and animal cells is separately patentable from Drs. Doudna and Charpentier's invention of the use of CRISPR-Cas9 in any environment. We are evaluating further litigation options. We also look forward to proving that Drs. Doudna and Charpentier first invented usage in plant and animal cells – a fact that is already widely recognized by the global scientific community – as the Doudna-Charpentier team's several pending patent applications that cover use of CRISPR-Cas9 in plant and animal cells are now under examination by the patent office.
CRISPR-Cas9 inventor Jennifer Doudna, a UC Berkeley professor of chemistry and of molecular and cell biology, was awarded the 2018 Kavli Prize in Nanoscience today in Norway during a gala ceremony hosted by King Harald V. She shared the prestigious honor with her colleague Emmanuelle Charpentier, now at the Max Planck Institute for Infection Biology in Berlin, Germany, and another early CRISPR researcher, Virginijus Šikšnys of Vilnius University in Lithuania.
