title: Analysis of base substitutions induced by ultraviolet radiation in Escherichia coli.
abstract: A system for determining the precise specificity of mutagens operating on Escherichia coli has been described, and the results for UV irradiation have been presented. Attempts to correlate the base pairs preferentially mutated by UV light with pyrimidine-pyrimidine sequences are discussed.
