Abstract
DNA computing often requires oligonucleotides that do not produce erroneous cross-hybridizations. By using in vitro evolution, huge libraries of non-crosshybridizing oligonucleotides might be evolved in the test tube. As a first step, a fitness function that corresponds to non-crosshybridization has to be implemented in an experimental protocol. Therefore, a modified version of PCR that selects non-crosshybridizing oligonucleotides was designed and tested. Experiments confirmed that the PCR-based protocol did amplify maximally mismatched oligonucleotides selectively over those that were more closely matched. In addition, a reaction temperature window was identified in which discrimination between matched and mismatched might be obtained. These results are a first step toward practical manufacture of very large libraries of non-crosshybridizing oligonucleotides in the test tube.
