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.
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.

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]
Cas9 (CRISPR associated protein 9, formerly called Cas5, Csn1, or Csx12) is a 160 kilodalton protein which plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids, and is heavily utilized in genetic engineering applications.

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 ]
