Can Genetic Information Be Controlled By Light?
invictus
by invictus  10-10-2008   
  It has been known for many years that the individual bases that code the genetic information contained in DNA show a high degree of photostability, as the energy that they take up from UV radiation is immediately released again. Surprisingly, however, it is found that in DNA, which consists of many bases, those mechanisms are ineffective or only partially effective. It seems that the deactivation of UV-excited DNA molecules must instead occur by some completely different mechanisms specific to DNA, which are not yet understood.

 Avobenzone helps to block UV-A light, but does so as long as octinoxate is not in the sunscreen mix. Check your labels. (Other UV-A blacker, Zinc Oxide).
