A new study led by scientists at The Scripps Research Institute suggests that the replication process for DNAthe genetic instructions for living organisms that is composed of four bases (C, G, A and T)is more open to unnatural letters than had previously been thought. An expanded "DNA alphabet" could carry more information than natural DNA, potentially coding for a much wider range of molecules and enabling a variety of powerful applications, from precise molecular probes and nanomachines to useful new life forms.
