The frequency of different types of pairs and triads of sister cells with labelled or unlabelled cells in mitosis was determined at different times after short-term incubation with 3H-thymidine to establish whether the mitotic cycle and G2-period duration depends on the cell length. Out of two sister cells of the pair, the larger cell used to have shorter mitotic cycle and G2-period than the smaller one. No direct dependence of the different ratios between their lengths was, however, shown. This is due to the absence of direct correlation between the mitotic cycle and G2-period durations. Possible causes of the absence of such a correlation are discussed.
在用³H - 胸腺嘧啶核苷短期孵育后的不同时间，测定有丝分裂中标记或未标记细胞的不同类型姐妹细胞对和三联体的频率，以确定有丝分裂周期和G2期持续时间是否取决于细胞长度。在一对姐妹细胞中，较大的细胞通常比较小的细胞有更短的有丝分裂周期和G2期。然而，未显示它们长度之间不同比例的直接依赖性。这是由于有丝分裂周期和G2期持续时间之间不存在直接相关性。讨论了不存在这种相关性的可能原因。
