Abstract
At an early stage of replication, parental T4 DNA shows a loop structure often displaying two 3'-ended, single-stranded "whiskers", located in trans configuration at the branching-points. Several such loops have been observed within a single T4 molecule. Occasionally, reinitiation occurred in the middle of a loop, which suggests that the loop was growing in both directions.
摘要
在复制的早期阶段，亲代T4 DNA呈现出一种环状结构，常常显示出两个3'端的单链“须”，它们在分支点处以反式构型定位。在单个T4分子内已观察到几个这样的环。偶尔，重新起始会在环的中间发生，这表明环在两个方向上都在生长。
