Scripps research team creates simple chemical system that mimics DNA

Findings offer possible clues about primordial world, and could eventually lead to exotic new materialsLa Jolla, CA, June 11, 2009 -A team of Scripps Research scientists has created a new analog to DNA that assembles and disassembles itself without the need for enzymes. Because the new system comprises components that might reasonably be expected in a primordial world, the new chemical system
