from the results of dna determination and of thymidine-3h incorporation in `` '' pulse chase '' '' experiments , the three peaks of the sedimentogram are identified as those corresponding to nuclei being in g1- and g2-periods of cycles of diploid and tetraploid tumour subpopulations , and ranges between the peaks are identified as nuclear fractions corresponding to s-periods of cycles of both the subpopulations .
