Caltech Researchers Demonstrate Possible Primitive Mechanism of Chemical Info Self-Replication

May. 30, 2012

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.
