Figure 12: Magnetic field effect on the rate of DNA synthesis by pol β loaded with 24Mg2+ (on the left) and 25Mg2+ (on the right) ions. Tritium radioactivity A is measured as the number of counts/min/mg DNA. Yellow (left) columns refer to the experiments in the Earth magnetic field; magenta (right) columns refer to the experiments carried out in magnetic field 160 mT.
