A biological network in Saccharomyces cerevisiae prevents the deleterious effects of endogenous oxidative DNA damage.

abstract：:Two cyclin-dependent kinases have been identified in yeast and mammalian RNA polymerase II transcription initiation complexes. We find that the two yeast kinases are indistinguishable in their ability to phosphorylate the RNA polymerase II CTD, and yet in living cells one kinase is a positive regulator and the other a...
