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.

建于1929年的这所建筑，开始时为了生活作为两个复式单位，其中一个由著名艺术家周日里德·海特画廊最初居住。

"The duplexes were designed as lofts because I thought that the theme of a contemporary art gallery would match with these kinds of units," the architect said.

“双人间设计为阁楼，因为我认为当代艺术画廊的主题将与这种单元相匹配”，建筑师说道。
