Synthetic genetic polymers, broadly referred to as XNAs, can replicate and evolve just like their naturally occurring counterparts, DNA and RNA, according to a new study published today (April 19) in Science. The results of the research have implications not only for the fields of biotechnology and drug design, but also for research into the origins of life—on this planet and beyond.
“It’s a breakthrough,” said Gerald Joyce of The Scripps Research Institute in La Jolla, California, who was not involved in the study—“a beautiful paper in the realm of synthetic biology.”
“It shows that you don’t have to stick with the ribose and deoxyribose backbones of RNA and DNA in order to have transmittable, heritable, and evolvable information,” added Eric Kool of Stanford University, ...
