English: UVA rays are unable to penetrate bacterial cell due to high wavelength and subsequent low energy. UVB and UVC are able to penetrate through the cell and damage DNA due to their low wavelength and higher energies. This leads to formation of Reactive Oxygen Species such as Hydrogen Peroxide, as well as Pyrimidine dimers in DNA. Formation of these compounds result in disturbance of multiple pathways in the cell, and eventually cell death.
