Cas9 protein is a molecular scissors used in targeted gene editing. It is a type of protein called a CRISPR-associated (Cas) protein, which is found in bacteria and helps protect against viral infections. Cas9 is used in the CRISPR-Cas9 gene editing system, which allows researchers to make precise cuts in DNA to add, remove or replace specific genes. This technology has potential applications in fields such as medicine, agriculture, and biotechnology. It has been used to treat genetic diseases, create disease-resistant crops, and engineer microbes that can break down pollutants.
