Abstract: | Summary The polB1 and polA1 polB1 strains of E. coli K-12, wihch are deficient in DNA polymerase II and in DNA polymerases I and II, respectively, were found to have essentially the same sensitivity to anoxic or aerobic X-irradiation as their related wild-type and polA1 strains, respectively. Thus, DNA polymerase II appears to play no major role in the repair of X-ray damage. |
