title: [Preferential localization of cadmium on the iterative DNA sequences from cultured tissues of the crown gall of tobacco (Nicotiana tabacum, var. Wisconsis 38)].
abstract: Fractionation of total crown-gall tissue culture DNA from Nicotiana tabacum by Ag+-Cs2SO4 density gradient is described. Cadmium ions determination is performed in each fraction by anodic stripping voltammetry. The cadmium content of the DNA in the lightest density fractions is 100 to 1000 times higher than in the other fractions.
