Nanoscale spatial induction of ultraviolet photoproducts in cellular DNA by three-photon near-infrared absorption.

abstract：:The crucial role of ubiquitin signalling in genome-integrity maintenance was first recognized in 1987 by Stefan Jentsch and Alex Varshavsky, who showed that Rad6-the repair protein involved in DNA damage tolerance-is a ubiquitin-conjugating enzyme. Although this discovery inspired extensive research and led to the dis...
