ScienceBacterial defense system reportedly uses a protein as a DNA blueprint
A post attributes the finding to Stanford researchers, saying the DRT3 system uses amino acids in an enzyme to determine which DNA letters to add—without a DNA template or RNA guide.
TLDR
A post says Stanford researchers discovered that DRT3, a bacterial defense system, builds DNA during a viral attack without copying an existing genetic template. The account describes the protein itself as the blueprint, with specific amino acids determining which DNA letters are added. The author suggests the mechanism could have biotechnology applications if it can be engineered.
