We investigate the class of functions computable by uni-transitional Watson-Crick D0L systems: only one complementarity transition is possible during each derivation. The class is characterized in terms of a certain min-operation applied to Z-rational functions. We also exhibit functions outside the

The phenomenon known as Watson-Crick complementarity is basic both in the experiments and theory of DNA computing. While the massive parallelism of DNA strands makes exhaustive searches possible, complementarity constitutes a powerful computational tool. It is also very fruitful to view complementar
