EFFECTS OF INCORPORATED RADIOISOTOPES UPON THE STABILITY OF GENETIC MATERIALS

[摘要] The effects of incorporated P-32 upon the stability of genetic DNA was studied by using the transformation system of Bacillus subtilis. The DNA contained in average 0.28 P-32 atom in each molecule and lost its transforming activity more rapidly than the cold DNA which was stocked together with P-32. It seems that the genetic DNA becomes unstable when it incorporates P-32 and is stocked in alcohol.
