The field of molecular computing came to prominence in 1994 when Len Adleman described a DNA computer based on PCR (Science, 266:1021–4). Such computers could be useful for solving particular problems but are fairly inflexible. "The main problem is that PCR can amplify the wrong DNA sequences, so errors can build up and large useful computations are difficult to perform," says Thomas Schneider of the National Cancer Institute's Laboratory of Experimental and Computational Biology.
