>Are there new proteins this lets them make? I think for now we are still a ways off from this being interesting at the protein level. I would think you would need new tRNAs to recognize the new bases in-order to really utilize them at a protein level, and those tRNAs would need to bind to different amino acids than we currently have for there to be any new protein function that we can't already accomplish with ATCG. That being said, you can still do a lot of interesting stuff with nucleic acids like DNA and RNA, more and more research these days show they can do more than just encode information for proteins.
