A team of researchers has uncovered a new biological editing system that could potentially be even more precise than CRISPR gene editing.
. A biochemical characterization of the Fanzor proteins showed that they are DNA-cutting endonuclease enzymes that use nearby non-coding RNAs known as ωRNAs. These ωRNAs target particular sites in the genome, and it is the first time this mechanism has been found in eukaryotes like the clam, according to the authors.
“Nature is amazing. There’s so much diversity,” said Zhang. “There are probably more RNA-programmable systems out there, and we’re continuing to explore and will hopefully discover more.”Laura is a science news writer, covering a wide variety of subjects, but she is particularly fascinated by all things aquatic, paleontology, nanotechnology, and exploring how science influences daily life.
