Overview
CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea. This technology has been harnessed as a powerful tool for gene editing through the use of Cas9 enzymes, with far-reaching implications for fields such as medicine, agriculture, and biotechnology. CRISPR has been recognized through prestigious awards, such as the Breakthrough Prize.
📖 Definition & Core Concept
CRISPR is a naturally occurring defense mechanism found in prokaryotic organisms, which has been adapted for use in gene editing through the development of CRISPR-Cas9 technology.
🔬 How It Works (Mechanics)
The mechanics of CRISPR involve the use of a small RNA molecule, known as a guide RNA, to locate a specific sequence of DNA within a genome. The guide RNA is programmed to recognize a particular sequence of nucleotides, and once it finds a match, it recruits a Cas9 enzyme to cut the DNA at that site. This creates a double-stranded break in the DNA, which can then be repaired through a process known as non-homologous end joining (NHEJ) or homologous recombination (HR). By manipulating this process, researchers can introduce specific changes to the genome, such as the insertion or deletion of genes, using techniques such as gene knockout and gene knockin.
