Now this replicator may sound fantastic and it is science fiction…it least for now. But replicators actually exist in nature. We can see a great example every time a human baby is born: a baby is essentially replicated in a mere 9 months time. So, it is possible molecule for molecule to recreate a baby, and nature does it. We scientists are currently trying to figure out how exactly it is that nature does that. How does nature rearrange the molecules—cut and splice molecule for molecule — to create something as complex as a baby? We know that the body does it with what are called ribosomes which have a blueprint that is provided by DNA.
