“CRISPR” stands for “Clusters of Regularly Interspaced Short Palindromic Repeats.”
“CRISPR” is shorthand for “CRISPR-Cas9.”
Bacteria and archaea uses CRISPR- derived RNA and Cas proteins like Cas9.
This long named thing protects bacteria and archaea from the attack of viruses. This mechanism chops and thereby destroys the DNA of a foreign invader.
In short, CRISPRs are specialized stretches of DNA and the protein Cas9 is an enzyme that acts like a pair of molecular scissors which can cut definite parts of a DNA strand.
These mechanism and components are used for gene editing in complex higher organisms.
It is now a technology for editing and modifying DNA. It can potentially correct genetic defects, treating and preventing the spread of diseases.
Let’s find about it’s detailed structure in the next article.
