LiveScience.com has published an article regarding the research work done by Joseph Jacobson of the Molecular Machines group at MIT in developing minature robots that mimic the way living cells replicate DNA.

In order for a cell to replicate it’s DNA, enzymes known as polymerases in the nucleus read the structure of the DNA and assemble nucleotides, the basic building block of DNA floating in the nucleoplasm, in the correct order to match the original. In addition to being self-assembling, many DNA polymerases are self-correcting: able to excise incorrect sequences of nucleotides and continue building the chain in the correct order.
