The genetic basis for life on Earth may be stored in RNA and DNA, but scientists have now made six synthetic mimics of genetic material that are capable of recording, propagating, and evolving genetic information (Science, DOI: 10.1126/science.1217622).
The mimics could form a rudimentary basis for synthetic life and may have applications in materials science, molecular diagnostics, and therapeutics, comments Gerald F. . . .
