摘要：

It is shown that a double-stranded DNA can be opened by a force only if the force exceeds a critical value, and this unzipping is a critical phenomenon. From the results of an equivalent delocalization in a non-hermitian quantum mechanics problem we show the different scaling behaviours of unzipping by force and thermal melting. Based on this we make a postulate on the first step of replication of DNA.
