Studies on Bacillus substilis DNA Lesions Induced by Fast Neutron Radiation

  • The content of Bacillus substilis var. niger (ATCC 9372) DNA double-strand breaks induced by neutron radiation at different doses and different dose rates respectively, was measured and quantified by pulsed-field gel electrophoresis. By the analyses of DNA release percentage (PR), DNA breakage level (L), average molecular weight of breakage DNA and DNA fragment distribution, the results showed that DNA fragments were obviously distributed into two regions in the different irradiation condition. This suggestes that there are some sensitive points to neutron radiation in the Bacillus substilis var. niger molecule. The DNA release percentage, DNA breakage level and the content of DNA fragments in different region varied regularly in some extent with change of the neutron radiation dose or dose rate.

Abstract: The content of Bacillus substilis var. niger (ATCC 9372) DNA double-strand breaks induced by neutron radiation at different doses and different dose rates respectively, was measured and quantified by pulsed-field gel electrophoresis. By the analyses of DNA release percentage (PR), DNA breakage level (L), average molecular weight of breakage DNA and DNA fragment distribution, the results showed that DNA fragments were obviously distributed into two regions in the different irradiation condition. This suggestes that there are some sensitive points to neutron radiation in the Bacillus substilis var. niger molecule. The DNA release percentage, DNA breakage level and the content of DNA fragments in different region varied regularly in some extent with change of the neutron radiation dose or dose rate.
