What is CRISPR?

The video explains CRISPR, a revolutionary tool in molecular biology, initially identified in E. coli. CRISPR consists of short DNA repeats and unique spacer DNA, functioning as an immune system in bacteria against viruses. The CRISPR Cas9 system, developed by Jennifer Doudna and Emmanuelle Charpentier, uses a single Cas9 protein and a guide RNA to cut DNA at specific sites, allowing for gene inactivation or insertion. This technology holds potential for treating genetic disorders and engineering new genes.
