Once again, the pairing of bases is used to build the gene back. The yin fixes the yang, the image restores the original: with DNA, as with Dorian Gray, the prototype is constantly reinvigorated by its portrait. Proteins chaperone and coordinate the entire process—guiding the damaged strand to the intact gene, copying and correcting the lost information, and stitching the breaks together—ultimately resulting in the transfer of information from the undamaged strand to the damaged strand.
