失去特定的碱基互补配对，复制酶系就不能合成模板链的互补链，而是在经过复制叉后留下一个裂口。
Without specific base pairing , the replication enzymes cannot specify a complementary strand , and gaps are left after the passing of a replication fork .

我们提出，诱导信号受类周期调制的原因是细胞内有限几个复制叉在复制过程中间歇性遇到DNA损伤，以致诱导信号被非连续的触发。
We argue that single cell shows oscillatory modulation because a limited number of replication forks occasionally encounter DNA lesions and trigger the inducing signal .

Chromosomal DNA replication starts at the sites called Origins by forming replication forks .
