Short tile strands compete for positions on a long DNA scaffold; mismatched neighbours are disfavoured and the correct arrangement becomes the output.<\/p>\n

Programs included multiplication by three, division by two, 8-bit parity and addition of two 25-bit numbers, counted as a 100-bit computation.<\/p>\n

What is new<\/h2>\n

Designing the answer as the favoured equilibrium reduces the need for a separate error-correction circuit and prescribed reaction path. Small cases finished under a minute and were reused dozens of times.<\/p>\n

Does it use no energy<\/h2>\n

The molecular phase needs no continuous electrical power, but DNA synthesis, heating, cooling and measurement still consume energy.<\/p>\n

Is it practical now<\/h2>\n

The tasks are far simpler and slower than silicon computing. Its promise is molecular parallelism and compatibility with chemical environments.<\/p>\n

Next check<\/h2>\n

Larger programs must test accuracy, preparation cost and readout. In-cell diagnosis remains a future possibility, not a treatment demonstrated here.<\/p>\n
