CRISPR-associated systems

CRISPR-associated systems are natural defense mechanisms used by bacteria and archaea to protect against invading viruses. They work by recognizing specific sequences of viral DNA, then cutting and disabling the invader’s genetic material. Scientists have adapted this system as a powerful tool for precise gene editing in various organisms, including humans. By designing guide molecules, CRISPR can target and modify specific genes, enabling advancements in medicine, agriculture, and research. Overall, CRISPR systems are a highly accurate, flexible approach to editing DNA and understanding genetic functions.
