CRISPR is a technology that can alter genetic material (DNA) in living cells. Learn how it works, what it can do and what are the ethical and scientific questions it raises.
Diagram of the CRISPR prokaryotic antiviral defense mechanism [2]. CRISPR (/ ˈ k r ɪ s p ər /; acronym of clustered regularly interspaced short palindromic repeats) is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea. [3] Each sequence within an individual prokaryotic CRISPR is derived from a DNA fragment of a bacteriophage that had ...
CRISPR is a way of finding and altering a specific bit of DNA inside a cell. It can be used for scientific research, medicine, agriculture and more, but also raises ethical and environmental concerns.
Learn how CRISPR works, why it's a big deal, and what it can do for medicine, biotechnology, and the environment. A Q&A with bioengineer Stanley Qi on the past, present, and future of CRISPR.
Applications of CRISPR technology. CRISPR gene-editing technology has a wide array of research and medical applications. For example, in the laboratory, CRISPR systems can be used to modify genes in bacteria and in animal and plant models, enabling researchers to gain new understanding of the effects of genetic modification.Although preexisting genetic engineering technologies have allowed ...
The CRISPR/Cas9 system. 1 Clustered regularly interspaced palindromic repeats (CRISPR) refers to sequences in the bacterial genome. They afford protection against invading viruses, when combined with a series of CRISPR-associated (Cas) proteins. Cas9, one of the associated proteins, is an endonuclease that cuts both strands of DNA.
CRISPR. When I first learned about CRISPR about a decade ago, the technology and the future possibilities were just amazing. A few years after that, I had the joy of meeting Dr. Jennifer Doudna at a small meeting at NHGRI, and we knew at that time that we were talking to a future Nobel Prize winner and, indeed, she got that very recently.

What is CRISPR (pronounced "crisper") and why has it been controversial? How it works DNA is like the instruction manual for life on our planet, and CRISPR/Cas9 can target sites in genetic ...
CRISPR is a system that bacteria use to fight viruses, but scientists have adapted it to cut and modify DNA sequences. Learn how CRISPR works, who discovered it and how it has been used for gene therapy and crop enhancement.
