The effect of temperature on the growth rate and the pattern of chromosome replication during the division cycle of Escherichia coli B/r growing in various media was investigated. The time between divisions, the time for a round of replication (C), and the time between completion of a round and cell division (D) were threefold longer at 21 C than at 37 C. At all temperatures and in all media, D equalled one-half C, suggesting that a common mechanism controls chromosome replication and the progression of the cell toward division after completion of a round of replication.
研究了温度对在各种培养基中生长的大肠杆菌B/r分裂周期中生长速率和染色体复制模式的影响。在21℃时,两次分裂之间的时间、一轮复制所需的时间(C)以及一轮复制完成到细胞分裂之间的时间(D)比在37℃时延长了两倍。在所有温度和所有培养基中,D等于C的一半,这表明存在一种共同机制控制染色体复制以及一轮复制完成后细胞向分裂的进程。
