A time course of frequency of thymine dimer formation in DNA in Hypsibius dujardini and Ramazzottius varieornatus kept under light and dark conditions following UVC irradiation in the hydrated state.

(A) A dot blot image showing thymine dimer formation in the two species. (B, C) Percentage of thymine dimers formed following exposure to UVC radiation in R. varieornatus and H. dujardini respectively. Control means non-irradiated specimens. pUC 19 plasmid DNA was used as molecular standard. Each value is the mean±SD (n = 3).
