1. UV light damages DNA by the formation of pyrimidine dimers. Draw the detailed chemical structure of a pyrimidine dimer and explain why the formation of such aberrant structures results in tumor-enabling genomic instability. 2. Use your own words to define ultraviolet light. Include a comparison of naturally-occurring vs artificial UV. What is UV-A? UV-B? UV-C? Which one(s) is (are) the most damaging to DNA? Why? Which one(s) are most likely to lead to a mutation in skin cells? Why? What type of UV light is used in tanning beds?
