Karin Richter,Bettina Hurrelmannty characterise the action of many hormones which ultimately direct long-term changes in gene expression (1, 2). Thus, the properties of transcription factors and the signalling pathways which regulate them, constitute an essential link in the relay of temporal information.

In the UVB spectrum the cyclobutane pyrimidine dimers and 6-4 photoproduct are the main DNA lesions. In higher wavelengths active oxygen species may be responsible for DNA strand breaks (1).
