It’s the latest in a string of discoveries about the underlying structure of life and the building blocks that make it up. We’ve learned that life might not even need DNA to exist, and a potential means to create life of that DNA-less nature was recently demonstrated when scientists created enzymes in a lab without the stuff. Then, you’ve got scientists who have been able to create new nucleotides (the “letters” in DNA) that do not exist in nature and insert them into a living organism. And now, this: DNA can look like just about anything.
