Cas9 Protein

Cas9 protein is a naturally occurring enzyme originally found in bacteria, where it serves as a defense mechanism against viruses. In scientific research, scientists have harnessed Cas9 for gene editing because it can precisely cut DNA at specific locations guided by a small RNA molecule. This allows for targeted modifications to genes, enabling scientists to add, remove, or alter genetic information. Cas9’s precision and versatility make it a powerful tool for advances in medicine, agriculture, and biological research, helping to develop gene therapies, improve crops, and understand genetics more deeply.
