The different aspects of chromosomes in culture with B.U.D.R. are described. The times of B.U.D.R. action are 1/2, 1, 2 and 3 mitotic cycles. Four different aspects are obtained. For each time, 250 mitosis are studied, and classified. The results seem to confirm the semiconservative replication.
描述了用5-溴脱氧尿嘧啶核苷（B.U.D.R.）培养时染色体的不同方面。B.U.D.R.作用的时间为1/2、1、2和3个有丝分裂周期。得到了四个不同的方面。每次对250个有丝分裂进行研究并分类。结果似乎证实了半保留复制。
