(C-F) Rad6 binding to DNA depends on Rad18, Rad52 (C), Rad51 (D), Rad57 (E) but not Rad54 (F) as determined by ChEC analyses of asynchronous cell cultures without or with 0.05% MMS for 2 hours. Data information: DNA gel electrophoresis, DNA content (cell sorting) and quantification of DNA digestion profiles are shown. The experiments were repeated twice with similar results.
