WebCpf1's small size also makes it suitable for multiplexing and use in AAV. Scientists have also developed CRISPR editing technologies that do not rely on NHEJ or HDR: Base editors: Base editors directly convert bases without creating a double-strand break. This method displays higher efficiency than HDR-mediated editing. WebScientists can use CRISPR tools to create gene drives. Gene drives spread chosen genes through populations of sexually-reproducing organisms with short lifespans. For example, scientists could potentially use gene drives to spread a gene through many, many, many mosquitoes to stop them from transmitting malaria. While gene drives would not work ...
