CRISPR gene editing (CRISPR, pronounced / ˈ k r ɪ s p ə r / (crisper), refers to a clustered regularly interspaced short palindromic repeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified.
CRISPR gene editing is a revolutionary technology that allows for precise, targeted modifications to the DNA of living organisms. Developed from a natural defense mechanism found in bacteria, CRISPR-Cas9 is the most commonly used system, that allows "cutting" of DNA at specific locations and either delete, modify, or insert genetic material.

8 July – Mitochondria are gene-edited for the first time, using a new kind of CRISPR-free base editor , by a team of researchers. [68] [69] 8 July: Researchers report that they succeeded in using a genetically altered variant of R. sulfidophilum to produce spidroins, the main proteins in spider silk. [70]

He co-developed Multiplex Automated Genome Engineering (MAGE) and optimized CRISPR/Cas9, discovered by Jennifer Doudna and Emmanuelle Charpentier for engineering a variety of genomes ranging from yeast to human. [62] His laboratory's use of CRISPR in human induced pluripotent stem cells (hiPS) is the latest contender for precise gene therapy. [64]
Doudna was introduced to CRISPR by Jillian Banfield in 2006 who had found Doudna by way of a Google search, having typed "RNAi and UC Berkeley" into her browser, and Doudna's name came up at the top of the list. [37] [38] In 2012, Doudna and her colleagues made a new discovery that reduces the time and work needed to edit genomic DNA.
