WebApr 28, 2024 · Here we describe a strategy for increasing the efficiency of HDR in cells by using a chromatin donor template instead of a naked DNA donor template. The use of chromatin, which is the natural form of DNA in the nucleus, increases the frequency of HDR-edited clones as well as homozygous 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 ...
