Abstract
Single-strand DNA nicks are induced by uranyl nitrate or uranyl acetate in combination with long-wavelength (lambda approximately 420 nm) ultraviolet irradiation. The nicks occur randomly with respect to the DNA sequence. Using the lambda-repressor/ORI operator DNA system it is shown that uranyl salts can be used to photofootprint protein contacts with the DNA backbone.
