Damage and restoration of the DNA-membrane complex of the bacterium Bacillus subtilis after the action of gamma radiation.

Abstract

It was shown that the structural damages arising in DNA-membrane complexes (DMC) of the Bacterium Bacillus subtilis under the action of gamma radiation are reversible in the postradiation period. The ability of the bacteria to repair radiation damage to DMC is correlated with their radiosensitivity. It is suggested that the process of restoration of the DMC depends on the products of the Pol A and the rec A genes.
