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 ]
Ishino was born in Kyoto Prefecture, Japan.He received his BS, MS and PhD in 1981, 1983 and 1986, respectively, from Osaka University. [1] From 1987 to 1989, he served as a post-doctoral fellow in Dieter Söll's laboratory at Yale University.
Cas12a (CRISPR-associated protein 12a, previously known as Cpf1) is an RNA-guided endonuclease that forms an essential component of the CRISPR systems found in some bacteria and archaea. In its natural context, Cas12a targets and destroys the genetic material of viruses and other foreign mobile genetic elements , thereby protecting the host ...
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.
Francisco Juan Martínez Mojica [a] (born 5 October 1963) is a Spanish molecular biologist and microbiologist at the University of Alicante in Spain.He is known for his discovery of repetitive, functional DNA sequences in bacteria which he named CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats).
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 .

In December 2021, it was reported that the first CRISPR-gene-edited marine animal/seafood and second set of CRISPR-edited food has gone on public sale in Japan: two fish of which one species grows to twice the size of natural specimens due to disruption of leptin, which controls appetite, and the other grows to 1.2 the natural average size with ...
In 2020, Charpentier and American biochemist Jennifer Doudna of the University of California, Berkeley, were awarded the Nobel Prize in Chemistry "for the development of a method for genome editing" (through CRISPR). This was the first science Nobel Prize ever won by two women only. [4] [5] [6]
