Abstract
Deinococcus radiodurans is characterized by its extreme resistance to ionizing radiation. Although Mn+2 was taken up by the cells at a high speed, the absorption of Mn+2 by the cells did not affect their survival rate when irradiated by UV light. However, the Mn‐induced‐cell‐division (Mn‐CD) cells do lose their resistance to UV radiation. This can be explained by the fact that the Mn‐CD cells were less efficient to remove pyrimidine dimers on damaged DNA. We also found that there is no strand‐specific repair of the pol gene in this organism.Keywords
