Bacterial antiviral enzyme builds DNA repeats like telomerase

Leading the DRT10 research program

Bacteria fight viruses with an enzyme that writes repetitive DNA from an RNA template. The system, called DRT10, works much like telomerase, the enzyme that protects chromosome ends in humans and most other eukaryotes.

Notable Quotes

Instead of cutting DNA like CRISPR, or swapping one letter of genetic code like base editors, this system uses RNA as a template to write new sequences of DNA. That gives us a different starting point for building tools to engineer cells.
