Positive results from the bacterial DNA damage or repair tests indicate that the test substance causes DNA damage, which is expressed as differential cell killing or growth inhibition of repair deficient bacteria. The DNA damage tests do not measure DNA repair per se nor do they measure mutations. A positive result in a DNA damage test in the absence of a positive result in another system is difficult to evaluate in the absence of a better database.

Spectroscopic investigations in the UV concern areas of photobiology with an impact on photomedicine, e.g. light activation of enzymes, UV-radiation effects on the immune system and on cellular membranes, the interaction of drugs with DNA (Chapter 4.2.2 and 4.2.3) and the role of DNA damage and repair in mutagenesis and carcinogenesis. 

Mismatched bases (bases that do not form normal Watson-Crick base pairs) are recognized by enzymes of the mismatch repair system. Because neither of the bases in a mismatch is damaged, these repair enzymes must be able to determine which base of the mispair to correct.
