"XNA" (Not DNA or RNA) May Form Basis for Life on Exo-Planets

Synthetic biologists have discovered that six other molecules can could store genetic information and pass it on. A host of alternative nucleic acids have been made in labs over the years, but no one has made them work like DNA....

Strange cousins: Molecular alternatives to DNA, RNA offer new insight into life’s origins

Academics / General Science : Science Daily (3 years ago)

Scientists have been investigating properties of so-called Xenonucleic acids or XNA's. They have demonstrated for the first time that six of these unnatural nucleic acid polymers are capable of sharing information with DNA. One of t... Read Post

Synthetic XNA molecules can evolve and store genetic information, just like DNA

Academics / General Science : Not Exactly Rocket Science (3 years ago)

Out of all the possible molecules in the world, just two form the basis of life’s grand variety: DNA and RNA. They alone can store and pass on genetic information. Within their repetitive twists, these polymers encode the stuff of e... Read Post
