Messenger ribonucleic acid (mRNA) preparations from T4-infected cells formed in the presence or absence of putrescine have been characterized and compared. Hybrid competition experiments indicate that these mRNA molecules are derived from distinct genetic loci. The results are consistent with the hypothesis that putrescine might control differential transcription of the phage genome during morphogenesis. The data are also in accord with previously observed changes in the population of mRNA formed at different times after infection.
对在有或没有腐胺存在的情况下形成的来自T4感染细胞的信使核糖核酸(mRNA)制剂进行了表征和比较。杂交竞争实验表明,这些mRNA分子源自不同的基因位点。结果与腐胺可能在形态发生过程中控制噬菌体基因组的差异转录这一假设一致。这些数据也与先前观察到的感染后不同时间形成的mRNA群体的变化相符。
