When scientists think about the replication of information in chemistry, they usually have in mind something akin to what happens in living organisms when DNA gets copied: a double-stranded molecule that contains sequence information makes two new copies of the molecule. But researchers at the California Institute of Technology (Caltech) have now shown that a different mechanism can also be used to copy sequence information.
