Jennifer Doudna’s team found an ancient CRISPR ancestor in viruses using a never-before-seen 'gapped' DNA code; the smaller VIPR system can target broadly and may become a new gene-editing tool
- The discovery may also reshape ideas about where CRISPR came from.
- The researchers found VIPR systems in viruses that appear to use them against competing viruses, suggesting that viral competition helped shape this unusual molecular weapon.
- The genetic code is usually described as an orderly language, read one letter after another in precise three-letter units.
