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

Thus on top of the dependence on g-c content, the stability of pna-dna duplexes also depends on the purine fraction of the PNA strand.
因此，肽核酸- DNA二聚体的稳定性除了依赖g - C配对的含量外，还与肽核酸链上的嘌呤含量有关。

Built in 1929 the property began life as two duplexes, one of which was originally inhabited by the famous artist Sunday Reed before her move to Heide Gallery.
