A chip for single mismatches : Results obtained with a photochemical‐ligation‐based DNA chip for enhanced discrimination of single‐nucleotide polymorphisms (see scheme) show that the reaction takes place over a period of hours, with the 50 % stage reached within 10 minutes. A single mismatch in the target sequence yielded extremely little ligated product (a rate 10 3 ‐fold lower than for the complementary case).
