CRISPR-Cas Systems and Genome Editing Tools
CRISPR-Cas technology provides a precise, programmable editing tool for both DNA and RNA, demonstrating versatility with variants like Cas12 and Cas13. Advanced editing techniques such as base and prime editing allow for targeted modifications without double-stranded breaks, enhancing gene therapy possibilities. The challenges of safe delivery and ethical implications underscore the need for responsible application in therapeutic contexts.
