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.
In molecular biology, trans-activating CRISPR RNA (tracrRNA) is a small trans-encoded RNA. It was first discovered by Emmanuelle Charpentier in her study of the human pathogen Streptococcus pyogenes , a type of bacteria that causes harm to humanity. [ 1 ]
In 2003, Mojica wrote the first paper suggesting that CRISPR was an innate microbial immune system. The paper was rejected by a series of high-profile journals, including Nature , Proceedings of the National Academy of Sciences , Molecular Microbiology and Nucleic Acids Research , before finally being accepted by Journal of Molecular Evolution ...
The first human trials in the US for CRISPR gene editing are officially underway. A University of Pennsylvania in Philadelphia spokesman has confirmed to NPR that two cancer patients, one with ...
[39] [40] They made history as the first two women to share this award without a male contributor. [41] [5] In June 2021, the first, small clinical trial of intravenous CRISPR gene editing in humans concluded with promising results. [42] [43] In September 2021, the first CRISPR-edited food went on public sale in Japan.

Human Nature is a film documentary which presents an in-depth description of the gene editing process of CRISPR, and its possible implications.The film includes the perspective of the scientists who invented the process, and of the genetic engineers who are applying the process.
CRISPR RNA or crRNA is a RNA transcript from the CRISPR locus. [1] CRISPR-Cas (clustered, regularly interspaced short palindromic repeats - CRISPR associated systems) is an adaptive immune system found in bacteria and archaea to protect against mobile genetic elements , like viruses , plasmids , and transposons .
