事实上，当嘌呤存在于肽核酸的链上时，肽核酸- DNA二聚体的稳定性会大大增加。

In fact PNA - DNA duplexes show significantly increased stability when the purines are in the PNA strand.

这种三螺旋体的稳定性极高，以至于在同型嘧啶PNA靶向双链DNA嘌呤道时，能取代其中一条DNA链侵入双螺旋。

The stability of these triple helixes is so high that homopyrimidine PNA targeted to purine tracts of dsDNA invades the duplex by displacing one of the DNA strands.
