Abstract
Measurements of the inhibition of DNA synthesis in bacteria and the formation of thymine dimers by ultraviolet irradiation of the cells indicate that one thymine dimer per 350-IA strand of DNA acts as a block to further synthesis. In a sensitive strain of Escherichia coli the blocks are permanent. In a resistant strain the blocks are only temporary but recovery of synthesis is not the result of splitting dimers.Entities:
