Biological computer can decrypt images stored in DNA:

Californian and Israeli researchers have created a biological computer — a machine made from biological molecules — that successfully decoded two images stored and encrypted within DNA.

Storing data in DNA isn’t all that hard — its primary purpose is to store genetic data, after all — but creating a biological computer to decode those long strings of amino acids is impressive. We’re not talking about a molecular computer that’s comparable to the CPU in your PC, though; rather, the scientists created a simple Turing machine-like finite state automaton.

“Our biological computing device is based on the 75-year-old design by the English mathematician, cryptanalyst, and computer scientist Alan Turing,” says Ehud Keinan who led the research. In the original Turing machine, a long strip of paper contains data and instructions. The data is fed into the machine, and rules (software) decide what kind of computation is done to the data.

Basically, Keinan and co created a mixture of molecules in a test tube that were capable of performing the same, repeatable set of instructions on a helix of DNA. Encoded DNA goes into the biological computer and decoded DNA comes out the other. To track the progress of the machine, the DNA was tagged with fluorescent markers.
