Researchers Create Synthetic DNA/RNA That Can Evolve
2012-04-20 07:04:05

Researchers have created artificial genetic material known as Xenonucleic acids, or XNAs, that can store information and evolve over generations in a comparable way to DNA. The research, reported Friday in the journal Science, has implications for the fields of molecular medicine and biotechnology, and sheds new light on how molecules first replicated and assembled into life billions of years ago. Living systems owe their existence to the information-carrying molecules DNA and...

In the chemistry of the living world, a pair of nucleic acids–DNA and RNA–reign supreme. As carrier molecules of the genetic code, they provide all organisms with a mechanism for faithfully reproducing themselves as well as generating the myriad proteins vital to living systems. Yet according to John Chaput, a researcher at the Center for Evolutionary Medicine and Informatics, at Arizona State University´s Biodesign Institute®, it may not always have been so. Chaput...
