CRISPR has the revolutionary potential to alter gene expression by cutting DNA.
Now NmeCas9 is a protein that cuts not just DNA, but RNA.
This has scary potential for viruses (made from RNA), but having read very little (and I don’t think very much is known yet), but I am interested to see how this progresses.
Read about it here, and keep checking on NiB. I see myself writing more about this in the future.
