(a) Effects of various uvr mutations on frequency of illegitimate recombination. We measured the frequency of formation of λ Spi− phages with or without UV irradiation. Burst size is the number of total λ phage per cell. (b) Complememtation test of the UvrA and UvrB defect by uvrA+ and uvrB+ plasmids. We measured the frequency of formation of λ Spi− phages with the strains carrying the uvrA plasmid, pJA61 (pBR322-uvrA+), the uvrB plasmid, pNP10 (pBR322-uvrB+), or control plasmid pBR322 with or without UV irradiation.
