The genetic material of DNA contains shielding mechanisms to protect itself from the exposure to the UV light emitted by the sun. This is of crucial importance, since without photostability – i.e. without "programmed" defense mechanisms against UV irradiation – there would be a rapid degradation of DNA and RNA.
