[Are there pseudophototropic reactions in biology? Part 1: Some considerations on molecular repair (author's transl)].

The phenomenon of repair in light and darkness in biological systems is compared with the reactions of the pseudophototropy of synthetic macromolecules. The reactions of the pseudophototropy, that is the formation of terminal double bond sequences and their reactions which are effected through ultraviolet irradiation or oxidation, seem to be identical to the mechanism of DNA repair.
