Jennifer Anne Doudna ForMemRS (/ ˈ d aʊ d n ə /; [1] born February 19, 1964) [2] is an American biochemist who has pioneered work in CRISPR gene editing, and made other fundamental contributions in biochemistry and genetics.
CRISPR-Cas can immunize bacteria against certain phages and thus halt transmission. For this reason, Koonin described CRISPR-Cas as a Lamarckian inheritance mechanism. [159] However, this was disputed by a critic who noted, "We should remember [Lamarck] for the good he contributed to science, not for things that resemble his theory only ...
CRISPR interference (CRISPRi) is a genetic perturbation technique that allows for sequence-specific repression of gene expression in prokaryotic and eukaryotic cells. [1] It was first developed by Stanley Qi and colleagues in the laboratories of Wendell Lim , Adam Arkin, Jonathan Weissman , and Jennifer Doudna . [ 2 ]
Šikšnys and members of his laboratory perform biochemical, biophysical and structural studies of proteins involved in bacterial antiviral defense, including restriction endonucleases and CRISPR-Cas systems. Šikšnys has co-authored more than 90 scientific publications and filled 5 patent applications.
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.
In his new book “The Catalyst,” Thomas R. Cech talks about the Covid-19 vaccines, what RNA means for future health crises and how gene editing with CRISPR factors in.

The CRISPR-Cas12a system consist of a Cas12a enzyme and a guide RNA that finds and positions the complex at the correct spot on the double helix to cleave target DNA. CRISPR-Cas12a systems activity has three stages: [3] Adaptation: Cas1 and Cas2 proteins facilitate the adaptation of small fragments of DNA into the CRISPR array.
