[Comparative analysis of the spectrum of radiation-induced structural mutations in diploid and tetraploid cells of mouse bone marrow].
A comparative analysis of the spectrum of radiation-induced mutations was carried out in diploid mouse bone marrow cells and in tetraploid cells obtained from the latter by means of colchicine treatment. It is established that solitary chromatid deletions prevail among aberrations induced at the G2--S stage. This is the difference of the spectrum of induced chromatid rearrangements in animal cells from that in plant cells. It is assumed that the differences observed are caused by the specificity of supramolecular organization of chromatin in animal and plant  cells.
