[Laser-induced covalent cross-links in DNA].
Formation of cross-links and local denaturated sites in double-stranded DNA of bacteriophage CD under picosecond laser UV irradiation was investigated by fluorescent method. It is shown that passing from low-intensity UV irradiation with mercury lamp to high-intensity laser UV irradiation quantum, yield of cross-links formation increases by an order.
