Probe molecules containing the complementary DNA name of Boston (AGCCTGAC) are attached to an iron ball suspended in liquid. Because of Watson-Crick affinity, the probes capture DNA strands that contain Boston’s name (TCGGACTG). Strands missing Boston’s name are then discarded. The process is repeated with probe molecules encoding the complementary DNA name of Chicago. When all the computational steps are completed, the strands left will be those that encode the solution GCAGTCGGACTGGGCTATGTCCGA. Atlanta) and the Watson-Crick complement of the first name of the end city (GGCT for Detroit). These two primers worked in concert: the first alerted DNA polymerase to copy complements of sequences that had the right start city, and the second initiated the duplication of molecules that encoded the correct end city. PCR proceeds through thermocycling, repeatedly raising and lowering the temperature of the mixture in the test...
