WebAug 2, 2024 · S cientists have successfully used CRISPR, a tool that cuts DNA with more precision than any other genome editing technology, to fix a genetic defect in human embryos that can cause serious heart ... WebThe CRISPR system is the basis of adaptive immunity in bacteria and archaea. It utilizes Cas nucleases, which are enzymes that can bind and create double-stranded breaks (DSBs) in DNA. When a bacterium is infected by a virus, it uses a Cas nuclease to snip off a piece of viral DNA known as a protospacer.
