Are you talking about DNA computing? As far as I know, very little
*practical* work has been done since Adleman's famous use of DNA to
solve a simple instance of the Hamilton-path finding problem (I hope
I'm wrong), but there has been plenty of theoretical work done in the
field which shows that it is euqivalent to Turing-computability. It
might not look like bits/bytes and machines, but it is the same

DNA computers (or other chemical computers) have the advantage of a
small scale and massive parallelism, but they are somewhat limited by
diffusion speeds, the amount of mass you can handle (combinatorial
explosions happen even here) and similar practical stuff.
