从结构来看，RNA是单链结构。

Structurally, RNA is a single-stranded structure.

线粒体DNA不同步的D环复制形式导致了控制区局部形成三链结构，其单链的构造使其更易受到过氧化物的损害。

Second, it has a triple strand DNA architecture generated by the synthesis of a short piece of the H strand which is highly sensitive to oxidative damage due to its single strand condition.

But they will do that in a very particular way, in that only strands that exactly match will be able to reform their native structure.

但是双链的形成也不是随意的,只有完全互补的单链之间,才成重新恢复到它们原先的结构

Hybridization simply means that DNA will re-nature and form a stable double helix only with its particular match, only with the hybrid that it is perfectly complementary, too.

核酸分子杂交表示,DNA在变性状态下可以恢复活性,和与其配对的单链形成稳定的双螺旋结构,只有在完全配对时才会发生这种情况
